Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In general, the Company’s provision for income taxes differs from the tax computed at the U.S. federal statutory income tax rate due to state taxes, the effect of non-U.S. operations, non-deductible stock-based compensation expense and adjustments to unrecognized tax benefits. For the three and nine months ended July 28, 2012, the Company recorded an income tax expense of $15.0 million and $11.1 million, respectively. The tax reported for both periods was impacted by the net effect of a decrease in benefit from the federal research and development tax credit which expired on December 31, 2011, partially offset by discrete benefits from reserve releases of settled tax audits, and the expiration of certain statutes of limitations. For the three and nine months ended July 30, 2011, the Company recorded an income tax benefit of $10.3 million and $16.6 million, respectively, primarily as a result of discrete benefits from the retroactive reinstatement of the federal research and development tax credit provision and reserve releases of settled tax audits, and the expiration of certain statutes of limitations. The total amount of unrecognized tax benefits of $103.2 million as of July 28, 2012 would affect the Company’s effective tax rate, if recognized. Although the timing of the closure of audits is highly uncertain, it is reasonably possible that the balance of unrecognized tax benefits could significantly change during the remainder of fiscal year 2012. The Internal Revenue Service (“IRS”) and other tax authorities regularly examine the Company’s income tax returns. The IRS is currently examining fiscal years 2009 and 2010. In addition, the IRS has also examined the Company’s income tax returns for fiscal years 2007 and 2008 and is contesting the Company’s transfer pricing for the cost sharing and buy-in arrangements with its foreign subsidiaries. The Company has filed a protest to appeal the amount of proposed adjustments in the Revenue Agent’s Report with the Appeals Office of the IRS. The Company believes it has sufficient reserves recorded for the ultimate settlement amount on this issue.

We believe that our reserves for unrecognized tax benefits are adequate for all open tax years. The timing of the resolution of income tax examinations, as well as the amounts and timing of related settlements, is highly uncertain. The Company believes that before the end of fiscal year 2012, it is reasonably possible that either certain audits will conclude or the statutes of limitations relating to certain income tax examination periods will expire, or both. As such, after we reach settlement with the tax authorities, we expect to record a corresponding adjustment to our unrecognized tax benefits. Given the uncertainty as to settlement terms, the timing of payments and the impact of such settlements on other uncertain tax positions, the range of estimated potential decreases in underlying uncertain tax positions is between $0 and $23 million in the next twelve months. The Company believes that sufficient positive evidence exists from historical operations and projections of taxable income in future years to conclude that it is more likely than not that the Company will realize its deferred tax assets. Accordingly, the Company applies a valuation allowance only on the deferred tax assets relating to capital loss carryforwards, due to limited carryforward periods and the character of such tax attributes. The Governor of the State of California and the California state legislature have introduced tax proposals affecting future state income tax apportionment that may have a significant impact on our ability to realize certain California deferred tax assets.
