FOR IMMEDIATE RELEASE

ISSI ANNOUNCES FIRST FISCAL QUARTER 2008 RESULTS

San Jose, Calif.—January 31, 2008--Integrated Silicon Solution, Inc. (Nasdaq: ISSI) today reported its financial results for the first fiscal quarter ended December 31, 2007.

Revenue in the first fiscal quarter ended December 31, 2007 was $63.3 million, flat with our September 2007 quarter and up slightly from $62.1 million reported in the December 2006 quarter. Net income for the December 2007 quarter was $3.0 million, or $0.08 per diluted share. Net income includes a $0.8 million charge for FAS 123R stock option expense and a $0.5 million expense for fees associated with our recent tender offer. These results compare with net income for the December 2006 fourth quarter of $0.1 million, or $0.00 per diluted share, which included a $1.0 million charge for FAS 123R stock option expense, $1.8 million for legal and accounting fees associated with our stock option investigation, and a $0.6 million gain on sale of assets.

Operating income for the first fiscal quarter ended December 31, 2007 was $0.8 million which included the $0.8 million FAS 123R charge and $0.5 million for fees associated with our tender offer. This compares to an operating loss of ($1.9) million for the same quarter in 2006 which included a $1.0 million FAS 123R charge and $1.8 million for legal and accounting fees associated with our stock option investigation. Gross margins for the first fiscal 2008 quarter were 20.8%, which compares to 20.2% from the same quarter in fiscal 2007.

The Company’s cash, cash equivalents and short-term investments totaled $143.3 million at December 31, 2007, an increase of $9.5 million from September 30, 2007. This increase was primarily due to an increase in our accounts payable. The Company also recently announced the completion of a Tender Offer which ended January 3, 2008 in which we repurchased $70 million of our outstanding common stock. Payments for the tendered shares were made in January 2008 and will be reflected in our financial results for the quarter ending March 2008. The Company’s inventory at December 31, 2007 totaled $38.2 million, an increase of $6.1 million from September 30, 2007.

“This quarter, we achieved our revenue goals and expanded our margins despite another weak pricing environment in mainstream DRAM markets and softening demand in some of our end markets,” said Jimmy Lee, ISSI’s Chairman and CEO. “Demand in SRAM and our focus DRAM markets remained strong as we continued to reduce our exposure to the price sensitive commodity DRAM markets. We are excited to show another profitable quarter with positive operating earnings which demonstrates the success of our strategy,” added Mr. Lee.
