NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

The consolidated results of operations for the three months and six months ended September 30, 2012 are not necessarily indicative of the results to be expected for the entire fiscal year.

Significant accounting policies

The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

Litigation and settlement costs

From time to time, the Company is involved in legal actions. The Company currently is a party to pending legal proceedings which it is defending aggressively. See Note 6 for additional information regarding this pending litigation. There are many uncertainties associated with any litigation, and the Company may not prevail. The litigation, regardless of its eventual outcome, will be costly and time consuming and, should the outcome be adverse to the Company, could result in the Company being required to pay significant monetary damages. If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation, or the settlement of such litigation, is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with GAAP. However, the actual liability in any such litigation may be materially different from our estimates, which could require us to record additional costs.

Recent accounting pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") amended its guidance on the presentation of comprehensive income. Under the amended guidance, an entity has the option to present comprehensive income in either one continuous statement or two consecutive financial statements. A single statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income. In a two-statement approach, an entity must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income. The entity is also required to present on the face of its financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The option under previous guidance that permitted the presentation of components of other comprehensive income as part of the statement of changes in stockholders' equity has been eliminated. In December 2011, the FASB further amended its guidance to defer changes related to the presentation of reclassification adjustments indefinitely as a result of concerns raised by stakeholders that the new presentation requirements would be difficult for preparers and add unnecessary complexity to financial statements. The amendment (other than the portion regarding the presentation of reclassification adjustments which, as noted above, has been deferred indefinitely) was effective during the quarter ended June 30, 2012. The amendment impacted the presentation of the consolidated financial statements but did not

5

impact the Company's financial position, results of operations or cash flows.

NOTE 2—NET INCOME PER COMMON SHARE

The Company uses the treasury stock method to calculate the weighted average shares used in computing diluted net income per share. The following table sets forth the computation of basic and diluted net income per share:

	Three Months Ended September 30,				Six Months Ended September 30,
	2012		2011		2012		2011

NOTE 4—INCOME TAXES

The current portion of the Company’s unrecognized tax benefits at September 30, 2012 and March 31, 2012 was $0 and $599,000, respectively.  The long-term portion at September 30, 2012 and March 31, 2012 was $2,114,000 and $1,835,000, respectively, of which the timing of the resolution is uncertain.  As of September 30, 2012, $609,000 of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets.  The unrecognized tax benefit balance as of September 30, 2012 of $2,591,000 would affect the Company’s effective tax rate if recognized.  It is possible, however, that some months or years may elapse before an uncertain position for which the Company has established a reserve is resolved.

Management believes that it is reasonably possible that within the next twelve months the Company could have a reduction in uncertain tax benefits of up to $154,000, including interest and penalties, related to positions taken with respect to credits and loss carryforwards on previously filed tax returns.

The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the Condensed Consolidated Statements of Operations.

The Company is subject to taxation in the United States and various state and foreign jurisdictions.  Fiscal years 2009 through 2012 remain open to examination by federal and most state tax authorities. In the three months ended June 30, 2012,

8

the Company settled an examination by the California Franchise Tax Board. The tax provision for the six month period ended September 30, 2012 includes a discrete benefit of $168,000 associated with the net result of the settlement and the associated tax reserves, including interest to date.

The Company’s estimated annual effective income tax rate was approximately 29.3% and 21.6% as of September 30, 2012 and 2011, respectively.  The differences between the effective income tax rate and the applicable statutory U.S. income tax rate in each period were primarily due to the effects of the expiration of federal R&D credits, foreign tax rate differentials and tax free interest income, offset by stock-based compensation expense.

NOTE 5—FINANCIAL INSTRUMENTS

Fair value measurements

Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosure.  The guidance applies to all financial assets and financial liabilities that are measured on a recurring basis.  The guidance requires fair value measurement to be classified and disclosed in one of the following three categories:

Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities.  The fair value of available-for-sale securities included in the Level 1 category is based on quoted prices that are readily and regularly available in an active market.  As of September 30, 2012, the Level 1 category included money market funds of $14.2 million, which were included in cash and cash equivalents in the Condensed Consolidated Balance Sheet.

Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based on the market values obtained from an independent pricing service that were evaluated using pricing models that vary by asset class and may incorporate available trade, bid and other market information and price quotes from well established independent pricing vendors and broker-dealers. As of September 30, 2012, the Level 2 category included short-term investments of $32.2 million and long-term investments of $26.1 million, which were comprised of certificates of deposit, corporate debt securities and government and agency securities.

Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity’s own assumptions about market participants and pricing.  As of September 30, 2012, the Company had no Level 3 financial assets measured at fair value in the Condensed Consolidated Balance Sheet.

The fair value of financial assets and liabilities measured on a recurring basis is as follows (in thousands):

			Fair Value Measurement at Reporting Date Using

Short-term and long-term investments

All of the Company’s short-term and long-term investments are classified as available-for-sale.  Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations.  Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of accumulated other comprehensive income in the Condensed Consolidated Balance Sheets.  The Company had money market funds of $14.2 million and $11.3 million at September 30, 2012 and March 31, 2012, respectively, included in cash and cash equivalents in the Condensed Consolidated Balance Sheet.  The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when declines are determined to be other-than-temporary.

The following table summarizes the Company’s available-for-sale investments:

Total long-term investments	$	33,424	$	89	$	(16	)	$	33,497

The Company’s investment portfolio consists of both corporate and governmental securities that have a maximum maturity of three years. All unrealized gains are due to changes in interest rates and bond yields. Subject to normal credit risks, the Company has the ability to realize the full value of all these investments upon maturity.

As of September 30, 2012 and March 31, 2012, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $32,000 and $26,000, respectively.

As of September 30, 2012, contractual maturities of the Company’s available-for-sale non-equity investments were as follows:

	Cost		Fair Value

The Company classifies its short-term investments as “available-for-sale” as they are intended to be available for use in current operations.

NOTE 6—COMMITMENTS AND CONTINGENCIES

Indemnification obligations

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold and certain intellectual property rights. In each of these circumstances, the Company's indemnification obligations are conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party’s claims. Further, the Company’s obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements.

It is not possible to predict the maximum potential amount of future payments that may be required under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material effect on its business, financial condition, cash flows or results of operations.

11

Product warranties

The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs were not significant for the three months or six months ended September 30, 2012 or 2011.

Legal proceedings

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against the Company in the United States District Court for the District of Minnesota alleging that the Company's products, including its SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress. The complaint seeks unspecified damages for past infringement and a permanent injunction against future infringement. On June 10, 2011, Cypress filed a complaint against the Company with the United States International Trade Commission (the “ITC”). The ITC complaint, as subsequently amended, alleges infringement by the Company of three of the five patents involved in the District Court case and one additional patent and also alleges infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products. The ITC complaint seeks a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing the Company and the other respondents to cease and desist from selling or distributing such products in the United States. On July 21, 2011, the ITC formally instituted an investigation in response to Cypress's complaint. Two of the distributor-respondents and ten of the customer-respondents were subsequently dismissed from the investigation. The evidentiary hearing took place during the week of March 12, 2012. On October 25, 2012, Chief Administrative Law Judge Charles E. Bullock issued his initial determination in which he held that the importation of the Company's SRAM products, and products containing them, and the sale within the United States of such products, have not violated applicable federal law with respect to any of the four patents that Cypress had alleged were infringed. Either party may request a review of the initial determination by the full Commission. The target date for concluding the ITC investigation is February 25, 2013. The District Court case has been stayed pending the conclusion of the ITC proceeding. The Company believes that Judge Bullock's initial determination was correct and intends to continue to defend itself vigorously in both proceedings. However, the litigation process is inherently uncertain, and the Company may not prevail. Patent litigation is particularly complex and can extend for a protracted period of time, which can substantially increase the cost of such litigation. The Company has not recorded any loss contingency during fiscal 2011 or fiscal 2012 in connection with these legal proceedings as the Company cannot predict their outcome and cannot estimate the likelihood or potential dollar amount of any adverse results. However, an unfavorable outcome in these proceedings could have a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the outcome occurs and in future periods.

Selling, general and administrative	182		174		371		355
Total	$	560	$	515	$	1,122	$	1,025

As stock-based compensation expense recognized in the Condensed Consolidated Statement of Operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures in accordance with authoritative guidance.  The Company estimates forfeitures at the time of grant and revises the original estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The Company recognized related income tax benefits of $26,000 and $61,000, respectively, for the three months ended September 30, 2012 and 2011and $116,000 and $120,000, respectively, for the six months ended September 30, 2012 and 2011.  Windfall tax benefits realized from exercised stock options were $1,000 and $5,000, respectively, for the three months ended September 30, 2012 and 2011, and $6,000 and $58,000, respectively, for the six months ended September 30, 2012 and 2011.  Compensation cost capitalized within inventory at September 30, 2012 was insignificant. As of September 30, 2012, the Company’s total unrecognized compensation cost was $4.0 million, which will be recognized over a weighted average period of 2.08 years.  The Company calculated the fair value of stock-based awards in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Quarterly Report on Form 10-Q, and in particular the following Management’s Discussion and Analysis of Financial Condition and Results of Operations, includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (“the Exchange Act”).  These forward-looking statements involve risks and uncertainties.  Forward-looking statements are identified by words such as “anticipates,” “believes,” “expects,” “intends,” “may,” “will,” and other similar expressions.  In addition, any statements which refer to expectations, projections, or other characterizations of future events, or circumstances, are forward-looking statements.  Actual results could differ materially from those projected in the forward-looking statements as a result of a number of factors, including those set forth in this report under “Risk Factors,” those described elsewhere in this report, and those described in our other reports filed with the Securities and Exchange Commission (“SEC”).  We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date of this report, and we undertake no obligation to update these forward-looking statements after the filing of this report. You are urged to review carefully and consider our various disclosures in this report and in our other reports publicly disclosed or filed with the SEC that attempt to advise you of the risks and factors that may affect our business.

Overview

We are a fabless semiconductor company that designs, develops and markets static random access memories, or SRAMs, that operate at speeds of less than 10 nanoseconds, which we refer to as Very Fast SRAMs, and low latency dynamic random access memories, or LLDRAMs. Our products are sold primarily to manufacturers of networking and telecommunications equipment. We are subject to the highly cyclical nature of the semiconductor industry, which has experienced significant fluctuations, often in connection with fluctuations in demand for the products in which semiconductor devices are used. Beginning in fiscal 2001, the networking and telecommunications markets experienced an extended period of severe contraction, during which our operating results sharply declined. Between fiscal 2004 and fiscal 2006, demand for networking and telecommunications equipment recovered. During the first three quarters of fiscal 2007, demand for such equipment accelerated and, as a result, our operating results improved. In the fourth quarter of fiscal 2007 and the first quarter of fiscal 2008, revenues again declined due, in part, to the implementation of a “lean manufacturing” program by our largest customer, Cisco Systems. Our revenues have been substantially impacted by the fluctuations in sales to Cisco Systems, and we expect that future direct and indirect sales to Cisco Systems will continue to fluctuate significantly on a quarterly basis. The worldwide financial crisis and the resulting economic impact on the end markets we serve have adversely impacted our financial results since the second half of fiscal 2009, and we expect that the unsettled global economic environment will continue to affect our operating results in future periods. However, with no debt, substantial liquidity and a history of positive cash flows from operations, we believe we are in a better financial position than many other companies of our size.

Revenues.    Our revenues are derived primarily from sales of our Very Fast SRAM products. Sales to networking and telecommunications original equipment manufacturers, or OEMs, accounted for 75% to 80% of our net revenues during our last three fiscal years. We also sell our products to OEMs that manufacture products for defense applications such as radar and

15

guidance systems, for professional audio applications such as sound mixing systems, for test and measurement applications such as high-speed testers, for automotive applications such as smart cruise control and voice recognition systems, and for medical applications such as ultrasound and CAT scan equipment.

As is typical in the semiconductor industry, the selling prices of our products generally decline over the life of the product. Our ability to increase net revenues, therefore, is dependent upon our ability to increase unit sales volumes of existing products and to introduce and sell new products with higher average selling prices in quantities sufficient to compensate for the anticipated declines in selling prices of our more mature products. Although we expect the average selling prices of individual products to decline over time, we believe that, over the next several quarters, our overall average selling prices will increase due to a continuing shift in product mix to a higher percentage of higher price, higher density products. Our ability to increase unit sales volumes is dependent primarily upon increases in customer demand but, particularly in periods of increasing demand, can also be affected by our ability to increase production through the availability of increased wafer fabrication capacity from Taiwan Semiconductor Manufacturing Company, or TSMC, and Powerchip, our wafer suppliers, and our ability to increase the number of good integrated circuit die produced from each wafer through die size reductions and yield enhancement activities.

We may experience fluctuations in quarterly net revenues for a number of reasons. Historically, orders on hand at the beginning of each quarter are insufficient to meet our revenue objectives for that quarter and are generally cancelable up to 30 days prior to scheduled delivery. Accordingly, we depend on obtaining and shipping orders in the same quarter to achieve our revenue objectives. In addition, the timing of product releases, purchase orders and product availability could result in significant product shipments at the end of a quarter. Failure to ship these products by the end of the quarter may adversely affect our operating results. Furthermore, our customers may delay scheduled delivery dates and/or cancel orders within specified timeframes without significant penalty.

We sell our products through our direct sales force, international and domestic sales representatives and distributors. Revenues from product sales, except for sales to distributors, are generally recognized upon shipment, net of sales returns and allowances. Sales to consignment warehouses, who purchase products from us for use by contract manufacturers, are recorded upon delivery to the contract manufacturer. Sales to distributors are recorded as deferred revenues for financial reporting purposes and recognized as revenues when the products are resold by the distributors to the OEM. Sales to distributors are made under agreements allowing for returns or credits under certain circumstances. We therefore defer recognition of revenue on sales to distributors until products are resold by the distributor.

Cisco Systems, our largest OEM customer, purchases our products primarily through its consignment warehouses, SMART Modular Technologies, Jabil Circuit and Flextronics Technology, and also purchases some products through its contract manufacturers and directly from us. Historically, purchases by Cisco Systems have fluctuated from period to period. Based on information provided to us by Cisco Systems' consignment warehouses and contract manufacturers, purchases by Cisco Systems represented approximately 27%, 41%,37% and 35% of our net revenues in the six months ended September 30, 2012 and in fiscal 2012, 2011 and 2010, respectively. Our revenues have been substantially impacted by the fluctuations in sales to Cisco Systems, and we expect that future direct and indirect sales to Cisco Systems will continue to fluctuate significantly on a quarterly basis and that such fluctuations may significantly affect our operating results in future periods. To our knowledge, none of our other OEM customers accounted for more than 10% of our net revenues in fiscal 2012, 2011 or 2010.

Cost of Revenues.    Our cost of revenues consists primarily of wafer fabrication costs, wafer sort, assembly, test and burn-in expenses, the amortized cost of production mask sets, stock-based compensation and the cost of materials and overhead from operations. All of our wafer manufacturing and assembly operations, and a significant portion of our wafer sort testing operations, are outsourced. Accordingly, most of our cost of revenues consists of payments to TSMC, Powerchip and independent assembly and test houses. Because we do not have long-term, fixed-price supply contracts, our wafer fabrication and other outsourced manufacturing costs are subject to the cyclical fluctuations in demand for semiconductors. Cost of revenues also includes expenses related to supply chain management, quality assurance, and final product testing and documentation control activities conducted at our headquarters in Sunnyvale, California and our branch operations in Taiwan.

Gross Profit.    Our gross profit margins vary among our products and are generally greater on our higher density products and, within a particular density, greater on our higher speed and industrial temperature products. We expect that our overall gross margins will fluctuate from period to period as a result of shifts in product mix, changes in average selling prices and our ability to control our cost of revenues, including costs associated with outsourced wafer fabrication and product assembly and testing.

Research and Development Expenses.    Research and development expenses consist primarily of salaries and related expenses for design engineers and other technical personnel, the cost of developing prototypes, stock-based compensation and

16

fees paid to consultants. We charge all research and development expenses to operations as incurred. We charge mask costs used in production to costs of revenues over a 12-month period. However, we charge costs related to pre-production mask sets, which are not used in production, to research and development expenses at the time they are incurred. These charges often arise as we transition to new process technologies and, accordingly, can cause research and development expenses to fluctuate on a quarterly basis. We believe that continued investment in research and development is critical to our long-term success, and we expect to continue to devote significant resources to product development activities. Accordingly, we expect that our research and development expenses will increase in future periods, although such expenses as a percentage of net revenues may fluctuate.

Selling, General and Administrative Expenses.     Selling, general and administrative expenses consist primarily of commissions paid to independent sales representatives, salaries, stock-based compensation and related expenses for personnel engaged in sales, marketing, administrative, finance and human resources activities, professional fees, costs associated with the promotion of our products and other corporate expenses. We expect that our sales and marketing expenses will increase in absolute dollars in future periods as we continue to grow and expand our sales force but that, to the extent our revenues increase in future periods, these expenses will generally decline as a percentage of net revenues. We also expect that, in support of our anticipated growth, general and administrative expenses will continue to increase in absolute dollars for the foreseeable future. General and administrative expenses increased significantly in fiscal 2012, primarily as a result of substantial legal expenses related to our pending patent infringement and antitrust litigation with Cypress Semiconductor Corporation. These expenses were substantially reduced during the six months ended September 30, 2012 while the issuance of the initial determination in the ITC proceeding was pending. However, legal expenses related to the ITC proceeding may increase during the quarter ending December 31, 2012, depending on the nature and extent of any challenge to Judge Bullock's initial determination, and these expenses may again become substantial in future quarters if the patent litigation continues. Additionally, on July 6, 2012, the United States District Court for the Northern District of California issued its decision upholding the sufficiency of the claims asserted by us in our antitrust complaint against Cypress. The complaint, filed on July 22, 2011, charges Cypress with conducting an unlawful combination and conspiracy, by and through the QDR Consortium, to exclude us and other competitors from the market for high-performance SRAM devices known as fast synchronous Quad Data Rate (or QDR) SRAMs and Double Data Rate (or DDR) SRAMs. The decision in our favor will allow us to pursue pre-trial discovery on all of the antitrust claims alleged in our complaint. Accordingly, we are likely to incur substantial legal expenses pursuing our antitrust claims against Cypress Semiconductor Corporation over the next one to two years.

Results of Operations

The following table sets forth statement of operations data as a percentage of net revenues for the periods indicated:

	Three Months Ended September 30,				Six Months Ended September 30,

Provision for income taxes	3.2		1.7		1.8		3.1
Net income	7.0	%	8.0	%	6.3	%	11.3	%

Net Revenues.Net revenues decreased by 23.0% from $20.8 million in the three months ended September 30, 2011 to $16.0 million in the three months ended September 30, 2012 and from $43.8 million in the six months ended September 30, 2011 to $32.8 million in the six months ended September 30, 2012. The reduction in net revenues in both periods was due primarily to softness in orders from our top three customers, each of which does significant business in Europe, where ongoing economic turmoil has adversely affected capital spending for network equipment manufactured by our customers. Direct and indirect sales to Cisco Systems, our largest customer, decreased by $3.0 million from $7.9 million in the three months ended September 30, 2011 to $4.9 million in the three months ended September 30, 2012 and by $8.5 million from $17.5 million in the six months ended September 30, 2011 to $9.0 million in the six months ended September 30, 2012. Additionally, excess inventories accumulated by our customers in fiscal 2011 and in early fiscal 2012 were drawn down in late fiscal 2012 and the first six months of fiscal 2013, adversely affecting our revenues. We believe that our net revenues in the third and fourth quarters of fiscal 2012 and the first two quarters of fiscal 2013 were also negatively impacted by uncertainty regarding the outcome of our pending patent litigation with Cypress Semiconductor. We expect that the favorable initial determination in the ITC proceeding will reduce this market uncertainty, although it may continue to have some effect on our revenues over the next several quarters. Shipments of our SigmaQuad product line accounted for 36.0% of total shipments in the six months ended September 30, 2012 compared to 33.9% of total shipments in the six months ended September 30, 2011.

Cost of Revenues. Cost of revenues decreased by 24.9% from $11.7 million in the three months ended September 30, 2011 to $8.8 million in the three months ended September 30, 2012 and by 23.5% from $24.6 million in the six months ended September 30, 2011 to $18.8 million in the six months ended September 30, 2012. The decreases in both periods were primarily due to the corresponding decreases in net revenues. Cost of revenues included stock-based compensation expense of $87,000 and $83,000, respectively, for the three months ended September 30, 2012 and 2011 and $177,000 and $159,000, respectively, for the six months ended September 30, 2012 and 2011.

Gross Profit. Gross profit decreased by 20.5% from $9.1 million in the three months ended September 30, 2011 to $7.2 million in the three months ended September 30, 2012 and by 27.4% from $19.2 million in the six months ended September 30, 2011 to $14.0 million in the six months ended September 30, 2012. Gross margin increased from 43.6% in the three months ended September 30, 2011 to 45.0% in the three months ended September 30, 2012 and decreased from 43.9% in the six months ended September 30, 2011 to 42.6% in the six months ended September 30, 2012. The decreases in gross profit were primarily related to the decreased net revenues. The changes in gross margin were primarily related to changes in the mix of products and customers and the impact of reduced revenue on our fixed manufacturing costs.

Research and Development Expenses. Research and development expenses increased 6.4% from $2.7 million in the three months ended September 30, 2011 to $2.9 million in the three months ended September 30, 2012. This increase was primarily due to increases of $168,000 in payroll related expenses, $33,000 in stock-based compensation and lesser increases in facility related expenses and patent related legal expenses. Research and development expenses included stock-based

18

compensation expense of $291,000 and $258,000, respectively, for the three months ended September 30, 2012 and 2011. Research and development expenses increased 7.0% from $5.3 million in the six months ended September 30, 2011 to $5.7 million in the six months ended September 30, 2012. This increase was primarily due to increases of $301,000 in payroll related expenses, $63,000 in stock-based compensation and lesser increases in facility related expenses and patent related legal expenses.Research and development expenses included stock-based compensation expense of $574,000 and $511,000, respectively, for the six months ended September 30, 2012 and 2011.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased 36.5% from $4.4 million in the three months ended September 30, 2011 to $2.8 million in the three months ended September 30, 2012. This decrease was primarily due to a decrease of $1.6 million in legal fees related to the pending patent infringement and antitrust litigation involving Cypress Semiconductor Corporation. Selling, general and administrative expenses included stock-based compensation expense of $182,000 and $174,000, respectively, for the three months ended September 30, 2012 and 2011. Selling, general and administrative expenses decreased 25.1% from $7.8 million in the six months ended September 30, 2011 to $5.9 million in the six months ended September 30, 2012. This decrease was primarily related to a decrease of $2.0 million in legal fees related to the pending patent infringement and antitrust litigation involving Cypress Semiconductor Corporation and a decrease in independent sales representative commissions of $170,000. Selling, general and administrative expenses included stock-based compensation expense of $371,000 and $355,000, respectively, for the six months ended September 30, 2012 and 2011.

Interest and Other Income (Expense), Net. Interest and other income (expense), net increased 32.3%, from $99,000 in the three months ended September 30, 2011 to $131,000 in the three months ended September 30, 2012. Interest income decreased by $24,000 due to lower interest rates received on our cash and short-term and long-term investments. Offsetting this decrease was a foreign currency exchange gain of $23,000 for the three months ended September 30, 2012 compared to an exchange loss of $33,000 for the three months ended September 30, 2011. Interest and other income (expense), net increased 9.0% from $245,000 in the six months ended September 30, 2011 to $267,000 in the six months ended September 30, 2012. Interest income decreased by $40,000 due to lower interest rates received on our cash and short-term and long-term investments. Offsetting this decrease was a foreign currency exchange gain of $37,000 for the six months ended September 30, 2012 compared to an exchange loss of $26,000 for the six months ended September 30, 2011. The exchange gains and losses in each period were related to our Taiwan branch operations.

Provision for Income Taxes. The provision for income taxes increased from $348,000 in the three months ended September 30, 2011 to $505,000 in the three months ended September 30, 2012 and decreased from $1.4 million in the six months ended September 30, 2011 to $601,000 in the six months ended September 30, 2012. These changes were due primarily to the changes in pre-tax income for the respective periods. During the three months ended June 30, 2012, we settled a tax audit for less than the amount previously provided for resulting in a tax benefit of $168,000 that contributed to the decrease in the tax provision for the six months ended September 30, 2012 .

Net Income.  Net income decreased 32.0% from $1.7 million in the three months ended September 30, 2011 to $1.1 million in the three months ended September 30, 2012 and 58.4% from $4.9 million in the six months ended September 30, 2011 to $2.1 million in the six months ended September 30, 2012. These decreases were primarily due to the decreases in net revenues, gross profit and the changes in operating expenses discussed above.

Liquidity and Capital Resources

As of September 30, 2012, our principal sources of liquidity were cash, cash equivalents and short-term investments of $67.1 million compared to $58.7 million as of March 31, 2012.

Net cash provided by operating activities was $4.5 million for the six months ended September 30, 2012 compared to $5.3 million for the six months ended September 30, 2011.  The primary sources of cash in the current six month period were net income of $2.1 million and a reduction of $1.9 million in accounts receivable, offset by a decrease in accounts payable of $1.6 million, and increase in inventory of $907,000 and a decrease in accrued expenses and other liabilities of $759,000. The decrease in accounts payable was primarily due to decreased legal expenses related to the pending patent infringement and antitrust litigation involving Cypress Semiconductor Corporation in the six months ended September 30, 2012 compared to the six months ended September 30, 2011.

Net cash provided by investing activities was $1.5 million in the six months ended September 30, 2012 compared to net cash used by investing activities of $6.8 million in the six months ended September 30, 2011.  Investment activities in the six months ended September 30, 2012 consisted primarily of the purchase of state and municipal obligations, corporate notes

19

and certificates of deposit of $15.6 million and the purchase of property and equipment.  These uses were more than offset by sales and maturities of investments of $17.3 million. Investment activities in the six months ended September 30, 2011 consisted of the sales and maturities of investments of $14.2 million more than offset by the purchase of state and municipal obligations, corporate notes and certificates of deposit of $20.4 million.

Net cash used by financing activities in the six months ended September 30, 2012 primarily consisted of the repurchase of $3.2 million of our common stock at an average purchase price of $4.42 per share. Net cash provided by financing activities consisted primarily of the net proceeds from the sale of common stock pursuant to our employee stock plans.

We believe that our existing balances of cash, cash equivalents and short-term investments, and cash flow expected to be generated from our future operations will be sufficient to meet our cash needs for working capital and capital expenditures for at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. Our future capital requirements will depend on many factors, including the rate of revenue growth that we experience, the extent to which we utilize subcontractors, the levels of inventory and accounts receivable that we maintain, the timing and extent of spending to support our product development efforts and the expansion of our sales and marketing efforts and the extent of legal expenses that we incur in connection with our pending patent and antitrust litigation. Additional capital may also be required for the consummation of any acquisition of businesses, products or technologies that we may undertake. We cannot assure you that additional equity or debt financing, if required, will be available on terms that are acceptable or at all.

Contractual Obligations

The following table describes our contractual obligations as of September 30, 2012:

	Payments due by period
	Up to 1 year		1-3 years		3-5 years		More than 5 years		Total
Facilities leases	$	278,000	$	211,000	$	—	$	—	$	489,000
Wafer, test and mask purchase obligations	3,803,000		1,760,000		161,000		—		5,724,000
	$	4,081,000	$	1,971,000	$	161,000	$	—	$	6,213,000

As of September 30, 2012, the current portion of our unrecognized tax benefits was $0, and the long-term portion was $2,114,000.  The unrecognized tax benefits balance as of September 30, 2012 of $2,591,000 would affect our effective tax rate if recognized.  As of September 30, 2012, $609,000 of unrecognized tax benefits have been recorded as a reduction of net deferred tax assets. 

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

Off-Balance Sheet Arrangements

At September 30, 2012, we did not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Accordingly, we are not exposed to the type of financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Recent Accounting Pronouncements

In June 2011, the FASB amended its guidance on the presentation of comprehensive income. Under the amended guidance, we have the option to present comprehensive income in either one continuous statement or two consecutive financial statements. A single statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income. In a two-statement approach, we must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income. We are also required to present on the face of its financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The option under previous guidance that permited the presentation of components of other comprehensive income as part of the statement of changes in stockholders' equity has been eliminated. In December 2011, the FASB further amended its guidance to defer changes related to the presentation of reclassification adjustments indefinitely as a result of concerns raised by stakeholders that the new presentation requirements would be difficult for preparers and add unnecessary complexity to financial statements. The amendment (other than the portion regarding the presentation of reclassification adjustments which, as noted above, has been deferred indefinitely) was effective for the quarter ended June 30, 1012. The amendment impacted the presentation of the financial statements but did not impact our financial position, results of operations or cash flows.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Foreign Currency Exchange Risk. Our revenues and expenses, except those expenses related to our operations in Taiwan, including subcontractor manufacturing expenses, are denominated in U.S. dollars. As a result, we have relatively little exposure for currency exchange risks, and foreign exchange gains and losses have been minimal to date. We do not currently enter into forward exchange contracts to hedge exposure denominated in foreign currencies or any other derivative financial instruments for trading or speculative purposes. In the future, if we feel our foreign currency exposure has increased, we may consider entering into hedging transactions to help mitigate that risk.

21

Interest Rate Sensitivity.  We had cash, cash equivalents, short-term investments and long-term investments totaling $93.2 million at September 30, 2012. These amounts were invested primarily in money market funds, state and municipal obligations, corporate notes and certificates of deposit. The cash, cash equivalents and short-term marketable securities are held for working capital purposes. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. We believe a hypothetical 100 basis point increase or decrease in interest rates would not materially affect the fair value of our interest-sensitive financial instruments.  Declines in interest rates, however, will reduce future investment income.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Based on their evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of September 30, 2012, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report for the purpose of ensuring that the information required to be disclosed by us in this report is made known to them by others on a timely basis, and that the information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, in order to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized, and reported by us within the time periods specified in the SEC’s rules and instructions for Form 10-Q.

Changes in Internal Control over Financial Reporting.  There were no changes in our internal control over financial reporting that occurred during the three months ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1.Legal Proceedings

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against us in the United States District Court for the District of Minnesota alleging that our products, including our SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress. The complaint seeks unspecified damages for past infringement and a permanent injunction against future infringement.

On June 10, 2011, Cypress filed a complaint against GSI with the United States International Trade Commission (the “ITC”). The ITC complaint, as subsequently amended, alleges infringement by GSI of three of the five patents involved in the District Court case and one additional patent and also alleges infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products. The ITC complaint seeks a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing GSI and the other respondents to cease and desist from selling or distributing such products in the United States. On July 21, 2011, the ITC formally instituted an investigation in response to Cypress's complaint. Two of the distributor-respondents and ten of the customer-respondents were subsequently dismissed from the investigation. The evidentiary hearing took place during the week of March 12, 2012. On October 25, 2012, Chief Administrative Law Judge Charles E. Bullock issued his initial determination in which he held that the importation of our SRAM products, and products containing them, and the sale within the United States of such products, have not violated applicable federal law with respect to any of the four patents that Cypress had alleged were infringed. Either party may request a review of the initial determination by the full Commission. The target date for concluding the ITC investigation is February 25, 2013.The District Court case has been stayed pending the conclusion of the ITC proceeding.

On July 22, 2011, we filed a complaint against Cypress in the United States District Court for the Northern District of California. Our complaint alleges that Cypress has conducted an unlawful combination and conspiracy to monopolize the market for certain high-performance SRAM devices, known as fast synchronous Quad Data Rate (or QDR) SRAMs and Double Data Rate (or DDR) SRAMs. The complaint alleges that the anti-competitive, collusive and conspiratorial conduct of Cypress and certain co-conspirators has violated Section 1 of the Sherman Act and also constitutes unlawful restraint of trade and unfair competition under applicable provisions of California law. The complaint seeks treble damages, in an amount to be determined at trial, a preliminary and permanent injunction prohibiting the continuation of the unfair and illegal business practices and recovery of GSI's attorneys' fees and costs. Cypress moved to dismiss the complaint. On July 6, 2012, the Court denied Cypress' motion, upholding the sufficiency of the antitrust claims asserted in our complaint.

We believe that Judge Bullock's initial determination in the ITC proceeding was correct and we intend to continue to

22

defend ourselves vigorously in both patent infringement proceedings while vigorously continuing to prosecute our antitrust claims against Cypress. However, the litigation process is inherently uncertain, and we may not prevail. Patent litigation is particularly complex and can extend for a protracted period of time, which can substantially increase the cost of such litigation. We have incurred and expect to continue to incur substantial legal fees and expenses in connection with the Cypress patent and antitrust litigation, and we also expect the litigation to continue to divert the efforts and attention of some of our key management and technical personnel. As a result, the litigation, regardless of whether Judge Bullock's initial determination is sustained, will be costly and time consuming. In addition, we believe that uncertainty regarding the outcome of the litigation has caused some of our customers and potential customers to reduce purchases of our products and/or seek second sources of supply, which adversely affected our revenues during the past several quarters. We expect that Judge Bullock's favorable initial determination in the ITC proceeding will reduce this market uncertainty, although it may continue to have some effect on our revenues over the next several quarters.

Should the final outcome of the ITC proceeding be adverse to us, we and the other respondents could be prohibited from selling or distributing those of our products found to be infringing Cypress's patents, or end products containing them, in the United States, unless and until we are able to negotiate a license from Cypress. Should the District Court case resume and its outcome be adverse to us, we could be required to pay significant monetary damages to Cypress and could be enjoined from selling those of our products found to infringe Cypress's patents unless and until we are able to negotiate a license from Cypress. Any such license arrangement with Cypress would likely require the payment of royalties which would increase our cost of revenues and reduce our gross profit. If we and the other respondents are prohibited from selling our products, or end products containing them, in the United States, or if we are required to pay significant monetary damages, are enjoined from selling any of our products or are required to make substantial royalty payments pursuant to any such license arrangement, our business would be significantly harmed.

Item 1A. Risk Factors

Our future performance is subject to a variety of risks.  If any of the following risks actually occur, our business, financial condition and results of operations could suffer and the trading price of our common stock could decline.  Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations. You should also refer to other information contained in this report, including our condensed consolidated financial statements and related notes.  The risk factors described below do not contain any material changes from those previously disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

Unpredictable fluctuations in our operating results could cause our stock price to decline.

Our quarterly and annual revenues, expenses and operating results have varied significantly and are likely to vary in the future. For example, in the ten fiscal quarters ended September 30, 2012, we recorded net revenues of as much as $26.7 million and as little as $16.0 million and quarterly operating income of as much as $6.7 million and, in one quarter, an operating loss of $83,000. We therefore believe that period-to-period comparisons of our operating results are not a good indication of our future performance, and you should not rely on them to predict our future performance or the future performance of our stock price. In future periods, we may not have any revenue growth, or our revenues could decline. Furthermore, if our operating expenses exceed our expectations, our financial performance could be adversely affected. Factors that may affect periodic operating results in the future include:

• our ability to anticipate and conform to new industry standards;

• unpredictability of the timing and size of customer orders, since most of our customers purchase our products on a purchase order basis rather than pursuant to a long term contract;

• changes in our customers' inventory management practices;

• fluctuations in availability and costs associated with materials needed to satisfy customer requirements;

• manufacturing defects, which could cause us to incur significant warranty, support and repair costs, lose potential sales, harm our relationships with customers and result in write-downs;

• changes in our product pricing policies, including those made in response to new product announcements and pricing changes of our competitors; and

• our ability to address technology issues as they arise, improve our products' functionality and expand our product

23

offerings.

Our expenses are, to a large extent, fixed, and we expect that these expenses will increase in the future. We will not be able to adjust our spending quickly if our revenues fall short of our expectations. If this were to occur, our operating results would be harmed. If our operating results in future quarters fall below the expectations of market analysts and investors, the price of our common stock could fall.

Cisco Systems, our largest OEM customer, accounts for a significant percentage of our net revenues. If Cisco Systems, or any of our other major customers reduce the amount they purchase or stop purchasing our products, our operating results will suffer.

Cisco Systems, our largest OEM customer, purchases our products through its consignment warehouses and its contract manufacturers and directly from us. Based on information provided to us by its consignment warehouses and contract manufacturers, purchases by Cisco Systems represented approximately 41%, 37% and 35% of our net revenues in fiscal 2012, 2011 and 2010, respectively, and 27% in the six months ended September 30, 2012. We expect that our operating results in any given period will continue to depend significantly on orders from our key OEM customers, particularly Cisco Systems, and our future success is dependent to a large degree on the business success of these OEMs over which we have no control. We do not have long-term contracts with Cisco Systems or any of our other major OEM customers, distributors or contract manufacturers that obligate them to purchase our products. We expect that future direct and indirect sales to Cisco Systems will continue to fluctuate significantly on a quarterly basis and that such fluctuations may significantly affect our operating results in future periods. If we fail to continue to sell to our key OEM customers, distributors or contract manufacturers in sufficient quantities, our business could be harmed.

We have incurred significant losses in prior periods and may incur losses in the future.

We have incurred significant losses in prior periods. For example, in fiscal 2003 and 2004, we incurred losses of $7.4 million and $670,000, respectively. Although we have operated profitably during the last eight fiscal years, there can be no assurance that our Very Fast SRAMs will continue to receive broad market acceptance or that we will be able to consistently achieve period-to-period revenue growth or profitability. Our failure to do so may result in additional losses in the future. In addition, we expect our operating expenses to increase as we expand our business. If our revenues do not grow to offset these expected increased expenses, our business will suffer.

We depend upon the sale of our Very Fast SRAMs for most of our revenues, and a downturn in demand for these products could significantly reduce our revenues and harm our business.

We derive most of our revenues from the sale of Very Fast SRAMs, and we expect that sales of these products will represent the substantial majority of our revenues for the foreseeable future. Our business depends in large part upon continued demand for our products in the markets we currently serve, and adoption of our products in new markets. Market adoption will be dependent upon our ability to increase customer awareness of the benefits of our products and to prove their high-performance and cost-effectiveness. We may not be able to sustain or increase our revenues from sales of our products, particularly if the networking and telecommunications markets were to experience another significant downturn in the future. Any decrease in revenues from sales of our products could harm our business more than it would if we offered a more diversified line of products.

We are subject to the highly cyclical nature of the networking and telecommunications markets.

Our products are incorporated into routers, switches, wireless local area network infrastructure equipment, wireless base stations and network access equipment used in the highly cyclical networking and telecommunications markets. For example, our operating results declined sharply in fiscal 2002 and 2003 as a result of the severe contraction in demand for networking and telecommunications equipment in which our products are incorporated. Prior to this period of contraction, the networking and telecommunications markets experienced a period of rapid growth, which resulted in a significant increase in demand for our products. We expect that the networking and telecommunications markets will continue to be highly cyclical, characterized by periods of rapid growth and contraction. Our business and our operating results are likely to fluctuate, perhaps quite severely, as a result of this cyclicality.

We are subject to pending patent infringement litigation.

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against us alleging that our products, including our SigmaDDR and SigmaQuad families of Fast SRAMs, infringe five patents held by Cypress.

24

The complaint seeks unspecified damages for past infringement and a permanent injunction against future infringement. On June 10, 2011, Cypress filed a complaint against GSI with the ITC. The ITC complaint, as subsequently amended, alleges infringement by GSI of three of the five patents involved in the District Court case and one additional patent and also alleges infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products. The ITC complaint seeks a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing GSI and the other respondents to cease and desist from selling or distributing such products in the United States. On July 21, 2011, the ITC formally instituted an investigation in response to Cypress's complaint. The evidentiary hearing took place during the week of March 12, 2012. On October 25, 2012, Chief Administrative Law Judge Charles E. Bullock issued his initial determination in which he held that the importation of our SRAM products, and products containing them, and the sale within the United States of such products, have not violated applicable federal law with respect to any of the four patents that Cypress had alleged were infringed. Either party may request a review of the initial determination by the full Commission. The target date for concluding the ITC investigation is February 25, 2013. The District Court case has been stayed pending the conclusion of the ITC proceeding. We believe that we have strong defenses against Cypress's patent infringement claims and we intend to continue to defend ourselves vigorously in both proceedings. However, the litigation process is inherently uncertain, and we may not prevail. Patent litigation is particularly complex and can extend for a protracted period of time, which can substantially increase the cost of such litigation. We have incurred and expect to continue to incur substantial legal fees and expenses in connection with this litigation, and related antitrust litigation that we have commenced against Cypress, and we also expect the litigation to continue to divert the efforts and attention of some of our key management and technical personnel. As a result, the litigation, regardless of whether Judge Bullock's initial determination is sustained, will be costly and time consuming. In addition, we believe that uncertainty regarding the outcome of the litigation has caused some of our customers and potential customers to reduce their purchases of our products and/or seek alternative or second sources of supply, which adversely affected our revenues during the past several quarters. We expect that Judge Bullock's favorable initial determination in the ITC proceeding will reduce this market uncertainty, although it may continue to have some effect on our revenues over the next several quarters.

Should the final outcome of the ITC proceeding be adverse to us, we and the other respondents could be prohibited from selling or distributing those of our products found to be infringing Cypress's patents, or end products containing them, in the United States, unless and until we are able to negotiate a license from Cypress. Should the District Court case resume and its outcome be adverse to us, we could be required to pay significant monetary damages to Cypress and could be enjoined from selling those of our products found to infringe Cypress's patents unless and until we are able to negotiate a license from Cypress. Any such license arrangement with Cypress would likely require the payment of royalties which would increase our costs of revenues and reduce our gross profit. If we and the other respondents are prohibited from selling our products, or end-products containing them, in the United States, or if we are required to pay significant monetary damages, are enjoined from selling any of our products or are required to make substantial royalty payments pursuant to any such license arrangement, our business would be significantly harmed.

The average selling prices of our products are expected to decline, and if we are unable to offset these declines, our operating results will suffer.

Historically, the average unit selling prices of our products have declined substantially over the lives of the products, and we expect this trend to continue. A reduction in overall average selling prices of our products could result in reduced revenues and lower gross margins. Our ability to increase our net revenues and maintain our gross margins despite a decline in the average selling prices of our products will depend on a variety of factors, including our ability to introduce lower cost versions of our existing products, increase unit sales volumes of these products, and introduce new products with higher prices and greater margins. If we fail to accomplish any of these objectives, our business will suffer. To reduce our costs, we may be required to implement design changes that lower our manufacturing costs, negotiate reduced purchase prices from our independent foundries and our independent assembly and test vendors, and successfully manage our manufacturing and subcontractor relationships. Because we do not operate our own wafer foundry or assembly facilities, we may not be able to reduce our costs as rapidly as companies that operate their own foundries or facilities.

Current unfavorable economic and market conditions, domestically and internationally, may adversely affect our business, financial condition, results of operations and cash flows.

We have significant customer sales both in the United States and internationally. We are also reliant upon U.S. and international suppliers, manufacturing partners and distributors. We are therefore susceptible to adverse U.S. and international economic and market conditions, including the challenging economic conditions that have prevailed and continue to prevail in the United States and worldwide. The recent turmoil in the financial markets has resulted in higher borrowing costs and tightened credit markets which have made it more difficult (in some cases, prohibitively so) for many companies to fund their

25

working capital obligations. If any of our manufacturing partners, customers, distributors or suppliers experiences serious financial difficulties or ceases operations, our business could be adversely affected. The adverse impact of the credit crisis on consumers, including higher unemployment rates, is also adversely impacting consumer spending, which adversely impacts demand for consumer products, including certain end products in which our SRAMs are embedded. In addition, ongoing economic turmoil has recently had an adverse affect on capital expenditures for network equipment, particularly in Europe, which has impacted sales to some or our largest customers. The difficulty that businesses (including our customers) may have in obtaining credit, the decreased consumer spending resulting from the credit market crisis, high unemployment rates and continued global economic and market turmoil are likely to continue to have an adverse impact on our business, financial condition, results of operations and cash flows, at least over the near term.

We are dependent on a number of single source suppliers, and if we fail to obtain adequate supplies, our business will be harmed and our prospects for growth will be curtailed.

We currently purchase several key components used in the manufacture of our products from single sources and are dependent upon supply from these sources to meet our needs. If any of these suppliers cannot provide components on a timely basis, at the same price or at all, our ability to manufacture our products will be constrained and our business will suffer. Most significantly, we obtain wafers for our Very Fast SRAM products from a single foundry, TSMC, and most of them are packaged at ASE. Wafers for our LLDRAM products are obtained from Powerchip. If we are unable to obtain an adequate supply of wafers from TSMC or Powerchip or find alternative sources in a timely manner, we will be unable to fulfill our customer orders and our operating results will be harmed. We do not have supply agreements with TSMC, Powerchip, ASE or any of our other independent assembly and test suppliers, and instead obtain manufacturing services and products from these suppliers on a purchase-order basis. Our suppliers, including TSMC, have no obligation to supply products or services to us for any specific product, in any specific quantity, at any specific price or for any specific time period. As a result, the loss or failure to perform by any of these suppliers could adversely affect our business and operating results.

Should any of our single source suppliers experience manufacturing failures or yield shortfalls, be disrupted by natural disaster or political instability, choose to prioritize capacity or inventory for other uses or reduce or eliminate deliveries to us, we likely will not be able to enforce fulfillment of any delivery commitments and we would have to identify and qualify acceptable replacements from alternative sources of supply. In particular, if TSMC or Powerchip is unable to supply us with sufficient quantities of wafers to meet all of our requirements, we would have to allocate our products among our customers, which would constrain our growth and might cause some of them to seek alternative sources of supply. Since the manufacturing of wafers and other components is extremely complex, the process of qualifying new foundries and suppliers is a lengthy process and there is no assurance that we would be able to find and qualify another supplier without materially adversely affecting our business, financial condition and results of operations.

Because we outsource our wafer manufacturing and independent wafer foundry capacity is limited, we may be required to enter into costly long-term supply arrangements to secure foundry capacity.

We do not have long-term supply agreements with TSMC or Powerchip, but instead obtain our wafers on a purchase order basis. In order to secure future wafer supply from TSMC or Powerchip or from other independent foundries, we may be required to enter into various arrangements with them, which could include:

• contracts that commit us to purchase specified quantities of wafers over extended periods;

• investments in and joint ventures with the foundries; or

• non-refundable deposits with or prepayments or loans to foundries in exchange for capacity commitments.

We may not be able to make any of these arrangements in a timely fashion or at all, and these arrangements, if any, may not be on terms favorable to us. Moreover, even if we are able to secure independent foundry capacity, we may be obligated to use all of that capacity or incur penalties. These penalties may be expensive and could harm our financial results.

If we are unable to offset increased wafer fabrication costs by increasing the average selling prices of our products, our gross margins will suffer.

If there is a significant upturn in the networking and telecommunications markets that results in increased demand for our products and competing products, the available supply of wafers may be limited. As a result, we could be required to obtain additional manufacturing capacity in order to meet increased demand. Securing additional manufacturing capacity may cause our wafer fabrication costs to increase. If we are unable to offset these increased costs by increasing the average selling prices

26

of our products, our gross margins will decline.

We rely heavily on distributors and our success depends on our ability to develop and manage our indirect distribution channels.

A significant percentage of our sales are made to distributors and to contract manufacturers who incorporate our products into end products for OEMs. For example, in the six months ended September 30, 2012 and in fiscal 2012, 2011 and 2010, our distributor Avnet Logistics accounted for 28%, 20%, 17% and 22%, respectively, of our net revenues. Avnet Logistics and our other existing distributors may choose to devote greater resources to marketing and supporting the products of other companies. Since we sell through multiple channels and distribution networks, we may have to resolve potential conflicts between these channels. For example, these conflicts may result from the different discount levels offered by multiple channel distributors to their customers or, potentially, from our direct sales force targeting the same equipment manufacturer accounts as our indirect channel distributors. These conflicts may harm our business or reputation.

We may be unable to accurately predict future sales through our distributors, which could harm our ability to efficiently manage our resources to match market demand.

Our financial results, quarterly product sales, trends and comparisons are affected by fluctuations in the buying patterns of the OEMs that purchase our products from our distributors. While we attempt to assist our distributors in maintaining targeted stocking levels of our products, we may not consistently be accurate or successful. This process involves the exercise of judgment and use of assumptions as to future uncertainties, including end user demand. Inventory levels of our products held by our distributors may exceed or fall below the levels we consider desirable on a going-forward basis. This could result in distributors returning unsold inventory to us, or in us not having sufficient inventory to meet the demand for our products. If we are not able to accurately predict sales through our distributors or effectively manage our relationships with our distributors, our business and financial results will suffer.

A small number of customers generally account for a significant portion of our accounts receivable in any period, and if any one of them fails to pay us, our operating results will suffer.

At September 30, 2012, five customers accounted for 18%, 17%, 16%, 13% and 11% of our accounts receivable, respectively. If any of these customers do not pay us, our operating results will be harmed. Generally, we do not require collateral from our customers.

Our acquisition of companies or technologies could prove difficult to integrate, disrupt our business, dilute stockholder value and adversely affect our operating results.

In August 2009, we consummated the acquisition of substantially all of the assets related to the SRAM memory device product line of Sony Corporation. In the future, we may make additional acquisitions or investments in companies, assets or technologies that we believe are complementary or strategic. Prior to the Sony acquisition, we had not made any such acquisitions or investments, and therefore our experience as an organization in making such acquisitions and investments is limited. In connection with future acquisitions or investments we may make, we face numerous risks, including:

• difficulties in integrating operations, technologies, products and personnel;

• diversion of financial and managerial resources from existing operations;

• risk of overpaying for or misjudging the strategic fit of an acquired company, asset or technology;

• problems or liabilities stemming from defects of an acquired product or intellectual property litigation that may result from offering the acquired product in our markets;

• challenges in retaining key employees to maximize the value of the acquisition or investment;

• inability to generate sufficient return on investment;

• incurrence of significant one-time write-offs; and

• delays in customer purchases due to uncertainty.

27

If we proceed with additional acquisitions or investments, we may be required to use a considerable amount of our cash, or to finance the transaction through debt or equity securities offerings, which may decrease our financial liquidity or dilute our stockholders and affect the market price of our stock. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be harmed.

Claims that we infringe third party intellectual property rights could seriously harm our business and require us to incur significant costs.

In recent years, there has been significant litigation in the semiconductor industry involving patents and other intellectual property rights. We are currently involved in patent infringement litigation. See "We are subject to pending patent infringement litigation" above. We could become subject to additional claims or litigation in the future as a result of allegations that we infringe others' intellectual property rights or that our use of intellectual property otherwise violates the law. Claims that our products infringe the proprietary rights of others would force us to defend ourselves and possibly our customers, distributors or manufacturers against the alleged infringement. Any such litigation regarding intellectual property could result in substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. If any claims received in the future were to be upheld, the consequences to us would be severe and could require us to:

• stop selling our products that incorporate the challenged intellectual property;

• obtain a license to sell or use the relevant technology, which license may not be available on reasonable terms or at all;

• pay damages; or

• redesign those products that use the disputed technology.

Although patent disputes in the semiconductor industry have often been settled through cross-licensing arrangements, we may not be able in any or every instance to settle an alleged patent infringement claim through a cross-licensing arrangement. We have a more limited patent portfolio than many of our competitors. If a successful claim is made against us or any of our customers and a license is not made available to us on commercially reasonable terms or we are required to pay substantial damages or awards, our business, financial condition and results of operations would be materially adversely affected.

Our business will suffer if we are unable to protect our intellectual property.

Our success and ability to compete depends in large part upon protecting our proprietary technology. We rely on a combination of patent, trade secret, copyright and trademark laws and non-disclosure and other contractual agreements to protect our proprietary rights. These agreements and measures may not be sufficient to protect our technology from third-party infringement, or to protect us from the claims of others. Monitoring unauthorized use of our products is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Our attempts to enforce our intellectual property rights could be time consuming and costly. Litigation may be necessary in order to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. If competitors are able to use our technology without our approval or compensation, our ability to compete effectively could be harmed.

The market for Very Fast SRAMs is highly competitive.

The market for Very Fast SRAMs, which are used primarily in networking and telecommunications equipment, is characterized by price erosion, rapid technological change, cyclical market patterns and heightened foreign and domestic competition. Several of our competitors offer a broad array of memory products and have greater financial, technical, marketing, distribution and other resources than we have. Some of our competitors maintain their own semiconductor fabrication facilities, which may provide them with capacity, cost and technical advantages over us. We cannot assure you that we will be able to compete successfully against any of these competitors. Our ability to compete successfully in this market depends on factors both within and outside of our control, including:

• real or perceived imbalances in supply and demand of Very Fast SRAMs;

• the rate at which OEMs incorporate our products into their systems;

28

• the success of our customers' products;

• our ability to develop and market new products; and

• the supply and cost of wafers.

In addition, we are vulnerable to advances in technology by competitors, including new SRAM architectures and new forms of DRAM, or the emergence of new memory technologies that could enable the development of products that feature higher performance, lower cost or lower power capabilities. Additionally, the trend toward incorporating SRAM into other chips in the networking and telecommunications markets has the potential to reduce future demand for Very Fast SRAM products. There can be no assurance that we will be able to compete successfully in the future. Our failure to compete successfully in these or other areas could harm our business.

We may experience difficulties in transitioning to smaller geometry process technologies and other more advanced manufacturing process technologies, which may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

In order to remain competitive, we expect to continue to transition the manufacture of our products to smaller geometry process technologies. This transition will require us to migrate to new manufacturing processes for our products and redesign certain products. The manufacture and design of our products is complex, and we may experience difficulty in transitioning to smaller geometry process technologies or new manufacturing processes. These difficulties could result in reduced manufacturing yields, delays in product deliveries and increased expenses. We are dependent on our relationships with TSMC and Powerchip to transition successfully to smaller geometry process technologies and to more advanced manufacturing processes. We cannot assure you that TSMC or Powerchip will be able to effectively manage these transitions or that we will be able to maintain our relationship with them. If we or TSMC or Powerchip experience significant delays or fail to implement these transitions, our business, financial condition and results of operations could be materially and adversely affected.

Manufacturing process technologies are subject to rapid change and require significant expenditures for research and development.

We continuously evaluate the benefits of migrating to smaller geometry process technologies in order to improve performance and reduce costs. Historically, these migrations to new manufacturing processes have resulted in significant initial design and development costs associated with pre-production mask sets for the manufacture of new products with smaller geometry process technologies. For example, in fiscal 2010 and 2011, we incurred $650,000 and $727,000, respectively, in research and development expense associated with pre-production mask sets, which were not later used in production as part of the transition to our new 65 nanometer SRAM process technology and 72 nanometer DRAM process technology, respectively. We will incur similar expenses in the future as we continue to transition our products to smaller geometry processes. The transition costs inherent in the transition to new manufacturing process technologies will adversely affect our operating results and our gross margin.

Our products are complex to design and manufacture and could contain defects, which could reduce revenues or result in claims against us.

We develop complex products. Despite testing by us and our OEM customers, design or manufacturing errors may be found in existing or new products. These defects could result in a delay in recognition or loss of revenues, loss of market share or failure to achieve market acceptance. These defects may also cause us to incur significant warranty, support and repair costs, divert the attention of our engineering personnel from our product development efforts, result in a loss of market acceptance of our products and harm our relationships with our OEM customers. Our OEM customers could also seek and obtain damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend.

Defects in wafers and other components used in our products and arising from the manufacturing of these products may not be fully recoverable from TSMC or other suppliers. For example, in the quarter ended December 31, 2005, we incurred a charge of approximately $900,000 related to the write-off of inventory resulting from an error in the assembly process at one of our suppliers. This write-off adversely affected our operating results for fiscal 2006.

29

Demand for our products may decrease if our OEM customers experience difficulty manufacturing, marketing or selling their products.

Our products are used as components in our OEM customers' products. For example, Cisco Systems, our largest OEM customer, incorporates our products in a number of its networking routers and switches. Accordingly, demand for our products is subject to factors affecting the ability of our OEM customers to successfully introduce and market their products, including:

• capital spending by telecommunication and network service providers and other end users who purchase our OEM customers' products;

• the competition our OEM customers face, particularly in the networking and telecommunications industries;

• the technical, manufacturing, sales and marketing and management capabilities of our OEM customers;

• the financial and other resources of our OEM customers; and

• the inability of our OEM customers to sell their products if they infringe third-party intellectual property rights.

As a result, if OEM customers reduce their purchases of our products, our business will suffer.

Downturns in the semiconductor industry may harm our revenues and margins.

The semiconductor industry is highly cyclical. The industry has experienced significant downturns, often in connection with, or in anticipation of, maturing product cycles of both semiconductor companies' and their customers' products and declines in general economic conditions. These downturns have been characterized by production overcapacity, high inventory levels and accelerated erosion of average selling prices. From time to time, the semiconductor industry also has experienced periods of increased demand and production capacity constraints. Our operating results may suffer during the down portion of these cycles. Downturns in the semiconductor industry could cause our stock price to be volatile, and a prolonged decline in the industry could adversely affect our revenues. If we are unable to control our inventory levels or expenses adequately in response to reduced net sales, our results of operations would be negatively impacted.

If we do not successfully develop new products to respond to rapid market changes due to changing technology and evolving industry standards, particularly in the networking and telecommunications markets, our business will be harmed.

If we fail to offer technologically advanced products and respond to technological advances and emerging standards, we may not generate sufficient revenues to offset our development costs and other expenses, which will hurt our business. The development of new or enhanced products is a complex and uncertain process that requires the accurate anticipation of technological and market trends. In particular, the networking and telecommunications markets are rapidly evolving and new standards are emerging. We are vulnerable to advances in technology by competitors, including new SRAM architectures, new forms of DRAM and the emergence of new memory technologies that could enable the development of products that feature higher performance or lower cost. We may experience development, marketing and other technological difficulties that may delay or limit our ability to respond to technological changes, evolving industry standards, competitive developments or end-user requirements. For example, because we have limited experience developing integrated circuits, or IC, products other than Very Fast SRAMs, our efforts to introduce new products may not be successful and our business may suffer. Other challenges that we face include:

• our products may become obsolete upon the introduction of alternative technologies;

• we may incur substantial costs if we need to modify our products to respond to these alternative technologies;

• we may not have sufficient resources to develop or acquire new technologies or to introduce new products capable of competing with future technologies;

• new products that we develop may not successfully integrate with our end-users' products into which they are incorporated;

• we may be unable to develop new products that incorporate emerging industry standards;

• we may be unable to develop or acquire the rights to use the intellectual property necessary to implement new

30

technologies; and

• when introducing new or enhanced products, we may be unable to manage effectively the transition from older products.

Our products have lengthy sales cycles that make it difficult to plan our expenses and forecast results.

Our products are generally incorporated in our OEM customers' products at the design stage. However, their decisions to use our products often require significant expenditures by us without any assurance of success, and often precede volume sales, if any, by a year or more. If an OEM customer decides at the design stage not to incorporate our products into their products, we will not have another opportunity for a design win with respect to that customer's product for many months or years, if at all. Our sales cycle can take up to 24 months to complete, and because of this lengthy sales cycle, we may experience a delay between increasing expenses for research and development and our sales and marketing efforts and the generation of volume production revenues, if any, from these expenditures. Moreover, the value of any design win will largely depend on the commercial success of our OEM customers' products. There can be no assurance that we will continue to achieve design wins or that any design win will result in future revenues.

Any significant order cancellations or order deferrals could adversely affect our operating results.

We typically sell products pursuant to purchase orders that customers can generally cancel or defer on short notice without incurring a significant penalty. Any significant cancellations or deferrals in the future could materially and adversely affect our business, financial condition and results of operations. Cancellations or deferrals could cause us to hold excess inventory, which could reduce our profit margins, increase product obsolescence and restrict our ability to fund our operations. We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or incur significant charges against our income, which could materially and adversely affect our operating results.

As our business grows, such growth may place a significant strain on our management and operations and, as a result, our business may suffer.

We plan to continue expanding our business, and our expected growth could place a significant strain on our management systems, infrastructure and other resources. To manage the expected growth of our operations and increases in the number of our personnel, we will need to invest the necessary capital to improve our operational, financial and management controls and our reporting systems and procedures. Our controls, systems and procedures might not be adequate to support a growing public company. In addition, we may not have sufficient administrative staff to support our operations. For example, we currently have only five employees in our finance department in the United States, including our Chief Financial Officer. Furthermore, our officers have limited experience in managing large or rapidly growing businesses and the majority of our management had no previous experience in managing a public company or communicating with securities analysts and public company investors prior to the initial public offering of our common stock in 2007. If our management fails to respond effectively to changes in our business, our business may suffer.

Our international business exposes us to additional risks.

Products shipped to destinations outside of the United States accounted for 72%,77%, 70% and 69% of our net revenues in the six months ended September 30, 2012 and in fiscal 2012, 2011 and 2010, respectively. Moreover, we operate a facility in Taiwan, and a substantial portion of our products is manufactured and tested in Taiwan. We intend to continue expanding our international business in the future. Conducting business outside of the United States subjects us to additional risks and challenges, including:

• heightened price sensitivity from customers in emerging markets;

• compliance with a wide variety of foreign laws and regulations and unexpected changes in these laws;

• legal uncertainties regarding taxes, tariffs, quotas, export controls, competition, export licenses and other trade barriers;

• potential political and economic instability in, or foreign conflicts that involve or affect, the countries in which we, our customers and our suppliers are located;

31

• difficulties in collecting accounts receivable and longer accounts receivable payment cycles;

• difficulties and costs of staffing and managing personnel, distributors and representatives across different geographic areas and cultures, including assuring compliance with the U. S. Foreign Corrupt Practices Act and other U. S. and foreign anti-corruption laws;

• limited protection for intellectual property rights in some countries;

• heightened price sensitivity from customers in emerging markets; and

• fluctuations in freight rates and transportation disruptions.

Moreover, our reporting currency is the U.S. dollar. However, a portion of our cost of revenues and our operating expenses is denominated in currencies other than the U.S. dollar, primarily the New Taiwanese dollar. As a result, appreciation or depreciation of other currencies in relation to the U.S. dollar could result in transaction gains or losses that could impact our operating results. We do not currently engage in currency hedging activities to reduce the risk of financial exposure from fluctuations in foreign exchange rates.

TSMC and Powerchip, as well as our other independent suppliers and many of our OEM customers have operations in the Pacific Rim, an area subject to significant earthquake risk and adverse consequences related to the potential outbreak of contagious diseases such as the H1N1 Flu.

The foundries that manufacture our Very Fast SRAM and LLDRAM products, TSMC and Powerchip, and all of the principal independent suppliers that assemble and test our products are located in Taiwan. Many of our customers are also located in the Pacific Rim. The risk of an earthquake in these Pacific Rim locations is significant. The occurrence of an earthquake or other natural disaster near the fabrication facilities of TSMC or our other independent suppliers could result in damage, power outages and other disruptions that impair their production and assembly capacity. Any disruption resulting from such events could cause significant delays in the production or shipment of our products until we are able to shift our manufacturing, assembling, packaging or production testing from the affected contractor to another third-party vendor. In such an event, we may not be able to obtain alternate foundry capacity on favorable terms, or at all.

The outbreak of SARS in 2003 curtailed travel to and from certain countries, primarily in the Asia-Pacific region, and limited travel within those countries. If there were to be another outbreak of a contagious disease, such as SARS or the H1N1 Flu, that significantly affected the Asia-Pacific region, the operations of our key suppliers could be disrupted. In addition, our business could be harmed if such an outbreak resulted in travel being restricted, as it was during parts of 2003, or if it adversely affected the operations of our suppliers or our OEM customers or the demand for our products or our OEM customers' products.

Changes in Taiwan's political, social and economic environment may affect our business performance.

Because much of the manufacturing and testing of our products is conducted in Taiwan, our business performance may be affected by changes in Taiwan's political, social and economic environment. For example, any political instability resulting from the relationship among the United States, Taiwan and the People's Republic of China could damage our business. Moreover, the role of the Taiwanese government in the Taiwanese economy is significant. Taiwanese policies toward economic liberalization, and laws and policies affecting technology companies, foreign investment, currency exchange rates, taxes and other matters could change, resulting in greater restrictions on our ability and our suppliers' ability to do business and operate facilities in Taiwan. If any of these changes were to occur, our business could be harmed and our stock price could decline.

We are substantially dependent on the continued services and performance of our senior management and other key personnel.

Our future success is substantially dependent on the continued services and continuing contributions of our senior management who must work together effectively in order to design our products, expand our business, increase our revenues and improve our operating results. Members of our senior management team have long-standing and important relationships with our key customers and suppliers. The loss of services of Lee-Lean Shu, our President and Chief Executive Officer, Robert Yau, our Vice President of Engineering, any other executive officer or other key employee could significantly delay or prevent the achievement of our development and strategic objectives. We do not have employment contracts with, nor maintain key person insurance on, any of our executive officers.

32

If we are unable to recruit or retain qualified personnel, our business and product development efforts could be harmed.

We must continue to identify, recruit, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing and administrative personnel. Competition for these individuals is intense, and we may not be able to successfully recruit, assimilate or retain sufficiently qualified personnel. We may encounter difficulties in recruiting and retaining a sufficient number of qualified engineers, which could harm our ability to develop new products and adversely impact our relationships with existing and future end-users at a critical stage of development. The failure to recruit and retain necessary technical, managerial, sales, marketing and administrative personnel could harm our business and our ability to obtain new OEM customers and develop new products.

We may need to raise additional capital in the future, which may not be available on favorable terms or at all, and which may cause dilution to existing stockholders.

We may need to seek additional funding in the future. We do not know if we will be able to obtain additional financing on favorable terms, if at all. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, and we may be required to reduce operating costs, which could seriously harm our business. In addition, if we issue equity securities, our stockholders may experience additional dilution or the new equity securities may have rights, preferences or privileges senior to those of our common stock.

Our products are incorporated into advanced military electronics, and changes in international geopolitical circumstances and domestic budget considerations may hurt our business.

Some of our products are incorporated into advanced military electronics such as radar and guidance systems. Military expenditures and appropriations for such purchases have risen significantly in recent years. However, should the current conflict in Afghanistan and the general war on terror subside, our operating results would likely suffer. Domestic budget considerations may also adversely affect our operating results. For example, if governmental appropriations for military purchases of electronic devices that include our products are reduced, our revenues will likely decline.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements could be impaired, which could adversely affect our operating results, our ability to operate our business and investors' views of us.

Ensuring that we have adequate internal financial and accounting controls and procedures in place so that we can produce accurate financial statements on a timely basis is a costly and time-consuming process. On a continuous basis, we update our internal controls documentation and, where appropriate, improve our internal controls and procedures. Section 404 of the Sarbanes-Oxley Act of 2002 requires annual management assessments of the effectiveness of our internal control over financial reporting and a report by our independent registered public accounting firm addressing the effectiveness of our internal control over financial reporting. Both we and our independent registered public accounting firm test our internal controls and, as part of that documentation and testing process, identify areas for further attention and improvement. Implementing any appropriate changes to our internal controls may entail substantial costs in order to modify our existing financial and accounting systems, take a significant period of time to complete, and distract our officers, directors and employees from the operation of our business. These changes may not, however, be effective in maintaining the adequacy of our internal controls. Any failure to maintain that adequacy, or a consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs, materially impair our ability to operate our business, and adversely affect our stock price.

Our operations involve the use of hazardous and toxic materials, and we must comply with environmental laws and regulations, which can be expensive, and may affect our business and operating results.

We are subject to federal, state and local regulations relating to the use, handling, storage, disposal and human exposure to hazardous and toxic materials. If we were to violate or become liable under environmental laws in the future as a result of our inability to obtain permits, human error, accident, equipment failure or other causes, we could be subject to fines, costs, or civil or criminal sanctions, face property damage or personal injury claims or be required to incur substantial investigation or remediation costs, which could be material, or experience disruptions in our operations, any of which could have a material adverse effect on our business. In addition, environmental laws could become more stringent over time imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business.

We also face increasing complexity in our product design as we adjust to new and future requirements relating to the

33

materials composition of our products, including the restrictions on lead and other hazardous substances applicable to specified electronic products placed on the market in the European Union (Restriction on the Use of Hazardous Substances Directive 2002/95/EC, also known as the RoHS Directive). We also expect that our operations will be affected by other new environmental laws and regulations on an ongoing basis. Although we cannot predict the ultimate impact of any such new laws and regulations, they will likely result in additional costs, and could require that we change the design and/or manufacturing of our products, any of which could have a material adverse effect on our business.

The trading price of our common stock is subject to fluctuation and is likely to be volatile.

The trading price of our common stock may fluctuate significantly in response to a number of factors, some of which are beyond our control, including:

• actual or anticipated declines in operating results;

• changes in financial estimates or recommendations by securities analysts;

• the institution of legal proceedings against us or adverse developments in such proceedings;

• announcements by us or our competitors of financial results, new products, significant technological innovations, contracts, acquisitions, strategic relationships, joint ventures, capital commitments or other events;

• rapid changes in industry estimates in demand for Very Fast SRAM products;

• the gain or loss of significant orders or customers;

• recruitment or departure of key personnel; and

• market conditions in our industry, the industries of our customers and the economy as a whole.

In recent years the stock market in general, and the market for technology stocks in particular, have experienced extreme price fluctuations, which have often been unrelated to the operating performance of affected companies. The market price of our common stock might experience significant fluctuations in the future, including fluctuations unrelated to our performance. These fluctuations could materially adversely affect our business relationships, our ability to obtain future financing on favorable terms or otherwise harm our business. In addition, in the past, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. This risk is especially acute for us because the extreme volatility of market prices of technology companies has resulted in a larger number of securities class action claims against them. Due to the potential volatility of our stock price, we may in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert management's attention and resources. This could harm our business and cause the value of our stock to decline.

Our executive officers, directors and entities affiliated with them hold a substantial percentage of our common stock.

As of September 30, 2012, our executive officers, directors and entities affiliated with them beneficially owned approximately 26% of our outstanding common stock. As a result, these stockholders will be able to exercise substantial influence over, and may be able to effectively control, matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, which could have the effect of delaying or preventing a third party from acquiring control over or merging with us.

The provisions of our charter documents might inhibit potential acquisition bids that a stockholder might believe are desirable, and the market price of our common stock could be lower as a result.

Our Board of Directors has the authority to issue up to 5,000,000 shares of preferred stock. Our Board of Directors can fix the price, rights, preferences, privileges and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock might delay or prevent a change in control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders might be adversely affected. The issuance of preferred stock might result in the loss of voting control to other stockholders. We have no current plans to issue any shares of preferred stock. Our charter documents also contain other provisions, which might discourage, delay or prevent a merger or acquisition, including:

34

• our stockholders have no right to remove directors without cause;

• our stockholders have no right to act by written consent;

• our stockholders have no right to call a special meeting of stockholders; and

• stockholders must comply with advance notice requirements to nominate directors or submit proposals for consideration at stockholder meetings.

These provisions could also have the effect of discouraging others from making tender offers for our common stock. As a result, these provisions might prevent the market price of our common stock from increasing substantially in response to actual or rumored takeover attempts. These provisions might also prevent changes in our management. 

35

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Stock Repurchase Program

On November 6, 2008, our Board of Directors authorized us to repurchase, at management's discretion, up to $10 million of our common stock. On January 25, 2012, the Board authorized the repurchase of additional shares having an aggregate purchase price of up to $10 million. Under the repurchase program, we may repurchase shares from time to time on the open market or in private transactions. The specific timing and amount of the repurchases will be dependent on market conditions, securities law limitations and other factors. The repurchase program may be suspended or terminated at any time without prior notice. Below is a summary of our common stock repurchases during the quarter ended September 30, 2012.

Period	Shares Repurchased	Average Price Per Share	Value of Shares that May Yet Be Repurchased Under the Program

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The Company and Summary of Significant Accounting Policies

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

The consolidated results of operations for the three months and six months ended September 30, 2012 are not necessarily indicative of the results to be expected for the entire fiscal year.

Significant accounting policies

The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

Litigation and settlement costs

From time to time, the Company is involved in legal actions. The Company currently is a party to pending legal proceedings which it is defending aggressively. See Note 6 for additional information regarding this pending litigation. There are many uncertainties associated with any litigation, and the Company may not prevail. The litigation, regardless of its eventual outcome, will be costly and time consuming and, should the outcome be adverse to the Company, could result in the Company being required to pay significant monetary damages. If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation, or the settlement of such litigation, is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with GAAP. However, the actual liability in any such litigation may be materially different from our estimates, which could require us to record additional costs.

Recent accounting pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") amended its guidance on the presentation of comprehensive income. Under the amended guidance, an entity has the option to present comprehensive income in either one continuous statement or two consecutive financial statements. A single statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income. In a two-statement approach, an entity must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income. The entity is also required to present on the face of its financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The option under previous guidance that permitted the presentation of components of other comprehensive income as part of the statement of changes in stockholders' equity has been eliminated. In December 2011, the FASB further amended its guidance to defer changes related to the presentation of reclassification adjustments indefinitely as a result of concerns raised by stakeholders that the new presentation requirements would be difficult for preparers and add unnecessary complexity to financial statements. The amendment (other than the portion regarding the presentation of reclassification adjustments which, as noted above, has been deferred indefinitely) was effective during the quarter ended June 30, 2012. The amendment impacted the presentation of the consolidated financial statements but did not impact the Company's financial position, results of operations or cash flows.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

Indemnification obligations

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold and certain intellectual property rights. In each of these circumstances, the Company's indemnification obligations are conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party’s claims. Further, the Company’s obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements.

It is not possible to predict the maximum potential amount of future payments that may be required under these or similar agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material effect on its business, financial condition, cash flows or results of operations.

Product warranties

The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs were not significant for the three months or six months ended September 30, 2012 or 2011.

Legal proceedings

In March 2011, Cypress Semiconductor Corporation, a semiconductor manufacturer, filed a lawsuit against the Company in the United States District Court for the District of Minnesota alleging that the Company's products, including its SigmaDDR and SigmaQuad families of Very Fast SRAMs, infringe five patents held by Cypress. The complaint seeks unspecified damages for past infringement and a permanent injunction against future infringement. On June 10, 2011, Cypress filed a complaint against the Company with the United States International Trade Commission (the “ITC”). The ITC complaint, as subsequently amended, alleges infringement by the Company of three of the five patents involved in the District Court case and one additional patent and also alleges infringement by three of our distributors and 11 of our customers who allegedly incorporate our SRAMs in their products. The ITC complaint seeks a limited exclusion order excluding the allegedly infringing SRAMs, and products containing them, from entry into the United States and permanent orders directing the Company and the other respondents to cease and desist from selling or distributing such products in the United States. On July 21, 2011, the ITC formally instituted an investigation in response to Cypress's complaint. Two of the distributor-respondents and ten of the customer-respondents were subsequently dismissed from the investigation. The evidentiary hearing took place during the week of March 12, 2012. On October 25, 2012, Chief Administrative Law Judge Charles E. Bullock issued his initial determination in which he held that the importation of the Company's SRAM products, and products containing them, and the sale within the United States of such products, have not violated applicable federal law with respect to any of the four patents that Cypress had alleged were infringed. Either party may request a review of the initial determination by the full Commission. The target date for concluding the ITC investigation is February 25, 2013. The District Court case has been stayed pending the conclusion of the ITC proceeding. The Company believes that Judge Bullock's initial determination was correct and intends to continue to defend itself vigorously in both proceedings. However, the litigation process is inherently uncertain, and the Company may not prevail. Patent litigation is particularly complex and can extend for a protracted period of time, which can substantially increase the cost of such litigation. The Company has not recorded any loss contingency during fiscal 2011 or fiscal 2012 in connection with these legal proceedings as the Company cannot predict their outcome and cannot estimate the likelihood or potential dollar amount of any adverse results. However, an unfavorable outcome in these proceedings could have a material adverse impact on the Company's financial position, results of operations or cash flows for the period in which the outcome occurs and in future periods.

Fair Value Disclosures [Abstract]

Fair value measurements

Authoritative accounting guidance for fair value measurements provides a framework for measuring fair value and related disclosure.  The guidance applies to all financial assets and financial liabilities that are measured on a recurring basis.  The guidance requires fair value measurement to be classified and disclosed in one of the following three categories:

Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities.  The fair value of available-for-sale securities included in the Level 1 category is based on quoted prices that are readily and regularly available in an active market.  As of September 30, 2012, the Level 1 category included money market funds of $14.2 million, which were included in cash and cash equivalents in the Condensed Consolidated Balance Sheet.

Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based on the market values obtained from an independent pricing service that were evaluated using pricing models that vary by asset class and may incorporate available trade, bid and other market information and price quotes from well established independent pricing vendors and broker-dealers. As of September 30, 2012, the Level 2 category included short-term investments of $32.2 million and long-term investments of $26.1 million, which were comprised of certificates of deposit, corporate debt securities and government and agency securities.

Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity’s own assumptions about market participants and pricing.  As of September 30, 2012, the Company had no Level 3 financial assets measured at fair value in the Condensed Consolidated Balance Sheet.

The fair value of financial assets and liabilities measured on a recurring basis is as follows (in thousands):

			Fair Value Measurement at Reporting Date Using

Short-term and long-term investments

All of the Company’s short-term and long-term investments are classified as available-for-sale.  Available-for-sale debt securities with maturities greater than twelve months are classified as long-term investments when they are not intended for use in current operations.  Investments in available-for-sale securities are reported at fair value with unrecognized gains (losses), net of tax, as a component of accumulated other comprehensive income in the Condensed Consolidated Balance Sheets.  The Company had money market funds of $14.2 million and $11.3 million at September 30, 2012 and March 31, 2012, respectively, included in cash and cash equivalents in the Condensed Consolidated Balance Sheet.  The Company monitors its investments for impairment periodically and records appropriate reductions in carrying values when declines are determined to be other-than-temporary.

The following table summarizes the Company’s available-for-sale investments:

	September 30, 2012
	Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value

Other	2,758		—		(16		)	2,742
Total long-term investments	$	33,424	$	89	$	(16	)	$	33,497

The Company’s investment portfolio consists of both corporate and governmental securities that have a maximum maturity of three years. All unrealized gains are due to changes in interest rates and bond yields. Subject to normal credit risks, the Company has the ability to realize the full value of all these investments upon maturity.

As of September 30, 2012 and March 31, 2012, the deferred tax liability related to unrecognized gains and losses on short-term and long-term investments was $32,000 and $26,000, respectively.

As of September 30, 2012, contractual maturities of the Company’s available-for-sale non-equity investments were as follows:

	Cost		Fair Value
	(In thousands)
Maturing within one year	$	32,172	$	32,239
Maturing in one to three years	26,044		26,088
	$	58,216	$	58,327

The Company classifies its short-term investments as “available-for-sale” as they are intended to be available for use in current operations.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

Basis of presentation

The accompanying unaudited condensed consolidated financial statements of GSI Technology, Inc. and its subsidiaries (“GSI” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission.  Accordingly, the interim financial statements do not include all of the information and footnotes required by generally accepted accounting principles for annual financial statements.  These interim financial statements contain all adjustments (which consist of only normal, recurring adjustments) that are, in the opinion of management, necessary to state fairly the interim financial information included therein.  The Company believes that the disclosures are adequate to make the information not misleading.  However, these financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2012.

The consolidated results of operations for the three months and six months ended September 30, 2012 are not necessarily indicative of the results to be expected for the entire fiscal year.

Recent accounting pronouncements

Recent accounting pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") amended its guidance on the presentation of comprehensive income. Under the amended guidance, an entity has the option to present comprehensive income in either one continuous statement or two consecutive financial statements. A single statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income. In a two-statement approach, an entity must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income. The entity is also required to present on the face of its financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. The option under previous guidance that permitted the presentation of components of other comprehensive income as part of the statement of changes in stockholders' equity has been eliminated. In December 2011, the FASB further amended its guidance to defer changes related to the presentation of reclassification adjustments indefinitely as a result of concerns raised by stakeholders that the new presentation requirements would be difficult for preparers and add unnecessary complexity to financial statements. The amendment (other than the portion regarding the presentation of reclassification adjustments which, as noted above, has been deferred indefinitely) was effective during the quarter ended June 30, 2012. The amendment impacted the presentation of the consolidated financial statements but did not impact the Company's financial position, results of operations or cash flows.

As stock-based compensation expense recognized in the Condensed Consolidated Statement of Operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures in accordance with authoritative guidance.  The Company estimates forfeitures at the time of grant and revises the original estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The Company recognized related income tax benefits of $26,000 and $61,000, respectively, for the three months ended September 30, 2012 and 2011and $116,000 and $120,000, respectively, for the six months ended September 30, 2012 and 2011.  Windfall tax benefits realized from exercised stock options were $1,000 and $5,000, respectively, for the three months ended September 30, 2012 and 2011, and $6,000 and $58,000, respectively, for the six months ended September 30, 2012 and 2011.  Compensation cost capitalized within inventory at September 30, 2012 was insignificant. As of September 30, 2012, the Company’s total unrecognized compensation cost was $4.0 million, which will be recognized over a weighted average period of 2.08 years.  The Company calculated the fair value of stock-based awards in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

INCOME TAXES

The current portion of the Company’s unrecognized tax benefits at September 30, 2012 and March 31, 2012 was $0 and $599,000, respectively.  The long-term portion at September 30, 2012 and March 31, 2012 was $2,114,000 and $1,835,000, respectively, of which the timing of the resolution is uncertain.  As of September 30, 2012, $609,000 of unrecognized tax benefits had been recorded as a reduction to net deferred tax assets.  The unrecognized tax benefit balance as of September 30, 2012 of $2,591,000 would affect the Company’s effective tax rate if recognized.  It is possible, however, that some months or years may elapse before an uncertain position for which the Company has established a reserve is resolved.

Management believes that it is reasonably possible that within the next twelve months the Company could have a reduction in uncertain tax benefits of up to $154,000, including interest and penalties, related to positions taken with respect to credits and loss carryforwards on previously filed tax returns.

The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the Condensed Consolidated Statements of Operations.

The Company is subject to taxation in the United States and various state and foreign jurisdictions.  Fiscal years 2009 through 2012 remain open to examination by federal and most state tax authorities. In the three months ended June 30, 2012, the Company settled an examination by the California Franchise Tax Board. The tax provision for the six month period ended September 30, 2012 includes a discrete benefit of $168,000 associated with the net result of the settlement and the associated tax reserves, including interest to date.

The Company’s estimated annual effective income tax rate was approximately 29.3% and 21.6% as of September 30, 2012 and 2011, respectively.  The differences between the effective income tax rate and the applicable statutory U.S. income tax rate in each period were primarily due to the effects of the expiration of federal R&D credits, foreign tax rate differentials and tax free interest income, offset by stock-based compensation expense.
