Organization, Consolidation and Presentation of Financial Statements [Abstract]
Income Tax Policy	The Company’s provision for income taxes for the three and nine months ended December 27, 2014 and December 28, 2013 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) for the three and nine months ended December 27, 2014 and December 28, 2013 The Company intends to maintain a valuation allowance against its domestic net deferred tax assets until sufficient positive evidence exists to support its full or partial reversal. The amount of the deferred tax assets actually realized could vary depending upon the amount of taxable income the Company is able to generate in the various taxing jurisdictions in which the Company operates.
Fair Value Measurements Policy	On a quarterly basis, the Company measures the fair value of its marketable securities, which are comprised of U.S. government/agency securities, auction rate securities (ARS), equity securities, and money market funds. Marketable securities are reported at fair value in cash and cash equivalents, short-term investments and long-term investments on the Company’s Condensed Consolidated Balance Sheet. The related unrealized gains and losses are included in accumulated other comprehensive income (loss), a component of shareholders’ equity, net of tax.
Operating Segment Policy	As of December 27, 2014, the Company’s reportable segments are CPG and MPG. As of December 27, 2014, CSG did not meet the quantitative threshold for an individually reportable segment under ASC 280-10-50-12 and is therefore included in the “Other operating segment” line in the following tables. CPG and MPG are separate reportable segments based on the organizational structure and information reviewed by the Company’s Chief Executive Officer, who is the Company’s chief operating decision maker (or CODM), and are managed separately based on the end markets and applications they support. The CODM allocates resources and assesses the performance of each operating segment primarily based on non-GAAP operating income (loss) and non-GAAP operating income (loss) as a percentage of revenue.
