Organization, Consolidation and Presentation of Financial Statements Disclosure	Organization and Summary of Significant Accounting Policies Organization These interim Condensed Consolidated Financial Statements are unaudited but reflect, in the opinion of management, all adjustments, consisting of normal recurring adjustments and accruals, necessary to present fairly the financial position of SanDisk Corporation and its subsidiaries (the “Company”) as of September 27, 2015 , the Condensed Consolidated Statements of Operations, the Condensed Consolidated Statements of Comprehensive Income and the Condensed Consolidated Statements of Cash Flows for the nine months ended September 27, 2015 and September 28, 2014 . Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the Company’s most recent Annual Report on Form 10‑K filed with the SEC on February 10, 2015 . The results of operations for the three and nine months ended September 27, 2015 are not necessarily indicative of the results to be expected for the entire year. Basis of Presentation. The Company’s fiscal year ends on the Sunday closest to December 31 and its fiscal quarters generally consist of 13 weeks. Fiscal year 2015 will include 53 weeks with 14 weeks in the fourth fiscal quarter, while fiscal year 2014 included 52 weeks. The third quarters of fiscal years 2015 and 2014 ended on September 27, 2015 and September 28, 2014 , respectively. For accounting and disclosure purposes, the exchange rates of 120.67 , 120.44 and 109.23 at September 27, 2015 , December 28, 2014 and September 28, 2014 , respectively, were used to convert Japanese yen to the U.S. dollar. Throughout the Notes to Condensed Consolidated Financial Statements, unless otherwise indicated, references to Net income refer to Net income attributable to common stockholders, references to years or annual periods are references to fiscal years, and references to quarters are references to our fiscal quarters. Pending Acquisition by Western Digital Corporation . On October 21, 2015 , the Company entered into a definitive agreement under which Western Digital Corporation (“ Western Digital ”) will acquire all of the outstanding shares of the Company for a combination of cash and stock . The offer values the Company’s common stock at $86.50 per share or a total equity value of approximately $19 billion , using a five-day volume weighted-average trading price ended on October 20, 2015 of $79.5957 per share of Western Digital common stock. The transaction has been approved by the boards of directors of both companies. In the merger, each issued and outstanding share of common stock of the Company will be converted into the right to receive the below consideration per share of the Company’s common stock, subject to reallocation as described further below (the ‘‘Per Share Merger Consideration’’): (A) If the previously announced investment in Western Digital by a subsidiary of Unisplendour Corporation Ltd. (“ Unis Investment ”) closes prior to the effective time of the merger (the “Effective Time”): (i) $85.10 per share in cash; and (ii) 0.0176 shares of Western Digital ’s common stock; or (B) If the Unis Investment has not closed or has been terminated, prior to the Effective Time: (i) $67.50 per share in cash; and (ii) 0.2387 shares of Western Digital ’s common stock. The above allocation between cash and shares of Western Digital’s common stock is subject to reallocation, at Western Digital’s election, if the amount of cash that the Company has available for use in the United States without payment of withholding or United States income taxes on the closing date of the merger falls short of a target cash amount of $4.049 billion , if the closing of the merger occurs before June 30, 2016, or $4.139 billion , if the closing occurs on or after June 30, 2016 (the “Closing Cash Shortfall’’). If Western Digital so elects, the cash portion of the Per Share Merger Consideration will be reduced by the Closing Cash Shortfall, divided by the number of shares of the Company’s common stock outstanding as of the closing date of the merger (the ‘‘Per Share Cash Reduction Amount’’), and Western Digital’s common stock portion of the Per Share Merger Consideration will be correspondingly increased by a number of shares of Western Digital’s common stock equal to the Per Share Cash Reduction Amount divided by $79.5957 . The treatment of Company stock options under the merger agreement with Western Digital will vary depending on whether the exercise price of such options exceeds the value of the Per Share Merger Consideration as of the closing date of the merger (the ‘‘Closing Merger Consideration Value’’), determined by the sum of (i) the cash portion of the applicable Per Share Merger Consideration and (ii) the value of the Western Digital common stock portion of the Per Share Merger Consideration based on the volume weighted-average trading price of the Western Digital common stock over the five trading days preceding the closing date. Under the merger agreement with Western Digital, Western Digital will assume all unvested and outstanding Company stock options, all unvested restricted stock units and all outstanding Company stock options with a per share exercise price that is greater than or equal to the Closing Merger Consideration Value (whether or not such options have vested) held by employees immediately prior to the closing of the merger. All such stock options and restricted stock units will be converted into Western Digital stock options and restricted stock units, respectively, pursuant to the exchange ratio set forth in the merger agreement, and subject to the same vesting schedule (including any acceleration of vesting) as such stock options and restricted stock units had prior to being converted. Upon exercise or vesting after the closing date, respectively, such stock options and restricted stock units will entitle the holder to receive shares of Western Digital common stock; provided, that, if Unis Investment has occurred, Western Digital may elect to settle some or all of stock options and restricted stock units in cash, based on Western Digital’s share price on the exercise date or vesting date, respectively. All vested Company stock options with an exercise price less than the Closing Merger Consideration Value, and all vested restricted stock units, after giving effect to any acceleration, will be canceled at the Effective Time in exchange for the Per Share Merger Consideration, reduced by the applicable exercise price with respect to Company stock options (with the exercise price first applied against the stock portion of the Per Share Merger Consideration). The transaction is subject to approval by the Company’s stockholders and, in the event that the Unis Investment in Western Digital does not close , Western Digital ’s shareholders, receipt of regulatory approvals and other customary closing conditions . If the merger agreement is terminated under specific circumstances, Western Digital or the Company may be required to pay the other party up to approximately $553 million . In addition, the merger agreement contains certain termination rights for the Company and Western Digital that will (a) require the Company to pay a fee to Western Digital of approximately $184 million if either Western Digital or the Company terminates the merger due to the Company’s stockholders’ failure to approve this merger; (b) require Western Digital to pay a fee to the Company of approximately $184 million if either Western Digital or the Company terminates the merger due to (i) the Unis Investment having not occurred or the Unis Investment having been terminated and (ii) Western Digital ’s stockholders’ failure to approve this merger; or (c) require Western Digital to pay a termination fee to the Company of approximately $1.060 billion if the merger is terminated due to failure to obtain certain required U.S. or foreign antitrust clearances. In connection with the merger, holders of the Company’s 1.5% Convertible Senior Notes due 2017 and the Company’s 0.5% Convertible Senior Notes due 2020 (collectively, the “ Notes ”) will have the right to convert their Notes for a period of time beginning 30-trading days prior to the anticipated closing of the merger. In addition, for a period of time following the closing of the merger, holders of the Notes will have the right to convert their Notes or to require the Company to repurchase their Notes . Holders that convert in connection with the merger will be entitled to an increase in the conversion rate, as specified in the indentures governing the Notes . The foregoing description of the merger agreement with Western Digital and the merger does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the merger agreement, a copy of which is attached as Exhibit 2.1 to the Form 8-K filed by the Company on October 26, 2015. Each of the Company and Western Digital will provide a joint proxy statement/prospectus to their respective stockholders. The Company and Western Digital also plan to file other documents with the SEC regarding the proposed merger. Investors are urged to read the joint proxy statement/prospectus and any other relevant documents that will be filed with the SEC carefully and in their entirety when they become available because they will contain important information about the proposed merger. The transaction is expected to close in the third calendar quarter of 2016 . Following completion of the merger, the Company will become a wholly owned subsidiary of Western Digital , the Company’s common stock will be delisted from The Nasdaq Stock Market and deregistered under the Securities Exchange Act of 1934, as amended, and as such, the Company will no longer file periodic reports with the SEC. Organization and Nature of Operations. The Company was incorporated in the State of Delaware on June 1, 1988. The Company designs, develops, markets and manufactures data storage solutions in a variety of form factors using its flash memory, controller and firmware technologies. The Company operates in one segment, flash memory storage products. Principles of Consolidation. The Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority stockholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries. The Condensed Consolidated Financial Statements also include the results of companies acquired by the Company from the date of each acquisition. Use of Estimates . The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenue, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, product returns, allowance for doubtful accounts, inventories and inventory valuation, valuation and impairments of marketable securities and investments, valuation and impairments of goodwill and long-lived assets, intellectual property (“IP”) claims, income taxes, warranty obligations, restructurings, contingencies, share-based compensation and litigation. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates. Revenue Recognition, Sales Returns and Allowances and Sales Incentive Programs. The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title and acceptance, if applicable, pricing is fixed or determinable and collectability is reasonably assured. Revenue is generally recognized at the time of shipment or transfer of title for customers not eligible for price protection and/or a right of return. Sales made to distributors and retailers are generally under agreements allowing price protection and/or a right of return and, therefore, the revenue and related costs of these transactions are deferred until the retailers or distributors sell-through the merchandise to their end customer or their rights of return expire. Estimated sales returns are recorded as a reduction to revenue and deferred revenue and were not material for any period presented in the accompanying Condensed Consolidated Financial Statements. The cost of shipping products to customers is included in cost of revenue. The Company recognizes expenses related to sales commissions in the period in which the commissions are earned. Revenue from patent licensing arrangements is recognized when earned, estimable and realizable. The timing of revenue recognition is dependent on the terms of each license agreement and on the timing of sales of licensed products. The Company generally recognizes royalty revenue when it is reported to the Company by its licensees, which is generally one quarter in arrears from the licensees’ sales of licensed products. For licensing fees that are not determined by the licensees’ sales, the Company generally recognizes license fee revenue on a straight-line basis over the life of the license. Some of the Company’s revenue arrangements are multiple-element arrangements because they are generally comprised of product, software and support services or multiple distinct licenses. For multiple-element arrangements, the Company evaluates whether each deliverable should be accounted for as a separate unit of accounting. For multiple-element arrangements that include support or software elements, the Company analyzes whether tangible products containing software and non-software components function together and therefore should be excluded from industry-specific software revenue recognition guidance. The Company allocates revenue to each element, or the software elements as a group, based on the relative selling price determined in accordance with the Company’s normal pricing and discounting practices for the specific element when sold separately for all multiple-element arrangements. For multiple-element license agreements that include more than one license to distinct technology that are separate units of accounting, the Company allocates revenue to each license based on the relative selling price of each deliverable. License fees related to existing technology with no continuing performance obligations are generally recognized upon license commencement and other license fees are generally recognized straight-line over the life of the license. The Company primarily uses an estimate of selling price to allocate revenue for multiple-element license agreements based upon similar licenses, historical and estimated future sales volume, duration, and market conditions. The Company records estimated reductions of revenue for customer and distributor incentive programs and offerings, including price protection, promotions, co-op advertising and other volume-based incentives and expected returns. All sales incentive programs are recorded as an offset to revenue or deferred revenue. Marketing development programs are recorded as a reduction to revenue.

Recent Accounting Pronouncements [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles	Recent Accounting Pronouncements In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015‑­16, “ Business Combinations, ” to simplify the accounting for measurement period adjustments. ASU 2015-16 requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The Company has early adopted ASU 2015‑­16 and this adoption did not have a material impact on its Consolidated Financial Statements. In July 2015, the FASB issued ASU 2015‑­11, “ Simplifying the Measurement of Inventory, ” to simplify measurement of inventory by measuring inventory at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. Net realizable value is defined as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. The Company has early adopted ASU 2015‑­11 and this adoption did not have a material impact on its Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015‑03, “ Interest-Imputation of Interest ,” to simplify the presentation of debt issuance costs by requiring that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts, whereas currently the debt issuance costs are presented as an asset. The Company expects to adopt ASU No. 2015‑03 in the fourth quarter of 2015. The Company does not believe the adoption of this guidance will have a material impact on its Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015‑05, “ Customer's Accounting for Fees Paid in a Cloud Computing Arrangement .” The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. Under application of this guidance, if a cloud computing arrangement includes a software license, the update specifies that the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. A customer should account for a cloud computing arrangement as a service contract if the arrangement does not include a software license. The Company expects to adopt ASU No. 2015‑05 in the first quarter of 2016. The Company is currently assessing the impact of this update. In May 2014, the FASB issued ASU No. 2014‑09, “ Revenue from Contracts with Customers .” Under this guidance, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. In July 2015, the FASB approved that this standard could be adopted in either the first quarter of 2017 or 2018 with earlier than 2017 adoption not permitted. Under application of the existing guidance, the Company’s sales made to distributors and retailers are generally deferred until the distributors or retailers sell the merchandise to their end customer. Under the new standard, the Company’s sales made to distributors and retailers are expected to be recognized upon transfer of inventory to the distributor or retailer resulting in earlier revenue recognition than per existing guidance with additional use of estimation. The Company is currently evaluating the appropriate transition method, timing of adoption and any further impact of this guidance on its Consolidated Financial Statements and related disclosures.

As of September 27, 2015 and December 28, 2014 , the Company had no financial assets or liabilities categorized as Level 3 and had not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted. Available-for-Sale Investments.

Available-for-sale securities that were in an unrealized gain position have been excluded from the table.

The gross unrealized loss on all available-for-sale fixed income securities at September 27, 2015 was considered temporary in nature. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, and the Company’s intent and ability to hold an investment for a period of time sufficient to allow for any anticipated recovery in market value. For debt security investments, the Company considered additional factors including the Company’s intent to sell the investments or whether it is “more likely than not” the Company will be required to sell the investments before the recovery of its amortized cost. The following table shows the realized gains and (losses) on sales of available-for-sale securities: Three months ended Nine months ended September 27, September 28, September 27, September 28, (In thousands) Realized gains $ 670 $ 3,388 $ 4,135 $ 8,098 Realized losses (611 ) (460 ) (1,557 ) (1,187 ) Net realized gains $ 59 $ 2,928 $ 2,578 $ 6,911 Fixed income securities by contractual maturity as of September 27, 2015 are shown below.

Derivative Instruments, Gain (Loss)
Derivative Instruments and Hedging Activities Disclosure	Derivatives and Hedging Activities Cash Flow Hedges. From time to time, the Company uses foreign exchange forward contracts designated as cash flow hedges to hedge a portion of future forecasted wafer purchases and research and development (“R&D”) expenses in Japanese yen. The gain or loss on the effective portion of a cash flow hedge is initially reported as a component of accumulated other comprehensive income (loss) (“AOCI”) and subsequently reclassified into cost of revenue or R&D expense in the same period or periods in which the cost of revenue or R&D expense is recognized, or reclassified into other income (expense) if the hedged transaction becomes probable of not occurring. Any gain or loss after a hedge is no longer designated, because it is no longer probable of occurring or related to an ineffective portion of a cash flow hedge, as well as any amount excluded from the hedge effectiveness, is recognized immediately as other income (expense). Net Investment Hedges. To help protect certain foreign currency denominated equity method investments from adverse changes in foreign currency exchange rates, the Company may enter into foreign currency forward contracts to partially hedge the changes in the carrying amounts of these investments due to fluctuations in foreign currency exchange rates. Foreign exchange forward contracts designated as net investment hedges relate to the underlying value of the Company’s equity method investments in Japanese yen. The effective portion of a net investment hedge is initially recorded in AOCI as a part of foreign currency translation. Cumulative gains and losses including forward points associated with foreign exchange forward contracts designated as net investment hedges would be reclassified to other income (expense) from AOCI upon sale or substantial liquidation of the foreign equity method investments. The ineffective portions of net investment hedges are recognized immediately as other income (expense). As of September 27, 2015 , the notional amount and unrealized gain and loss on the effective portion of the outstanding foreign exchange forward contracts to purchase Japanese yen that are designated as cash flow hedges and sell Japanese yen that are designated as net investment hedges are shown in both Japanese yen and U.S. dollar, based upon the exchange rate at September 27, 2015 , as follows: Notional Amount Unrealized Gain (Loss) (Japanese yen, in billions) (U.S. dollar, in thousands) (U.S. dollar, in thousands) Designated foreign exchange forward contracts: Cash flow hedges ¥ 18.3 $ 151,800 $ (91 ) Net investment hedges (20.0 ) (165,523 ) 1,065 Total designated foreign exchange forward contracts ¥ (1.7 ) $ (13,723 ) $ 974 As of September 27, 2015 , the maturities of the designated foreign exchange forward contract hedges were two months or less. Other Derivatives. Other derivatives that are non-designated consist primarily of foreign exchange forward contracts to minimize the risk associated with the foreign exchange effects of revaluing monetary assets and liabilities. Monetary assets and liabilities denominated in foreign currencies and the associated outstanding foreign exchange forward contracts were marked-to-market at September 27, 2015 with realized and unrealized gains and losses included in other income (expense). As of September 27, 2015 , the Company had foreign exchange forward contracts hedging balance sheet remeasurement exposures in British pounds, European euros, Japanese yen and Malaysian ringgits. Foreign exchange forward contracts were outstanding to buy and sell U.S. dollar-equivalents of approximately $414.3 million and $165.2 million in foreign currencies, respectively, based upon the exchange rates at September 27, 2015 . The amounts in the tables below include fair value adjustments related to the Company’s own credit risk and counterparty credit risk. Fair Value of Derivative Contracts. Gross fair value of derivative contracts was as follows: Derivative assets reported in Other Current Assets September 27, December 28, (In thousands) Foreign exchange forward contracts designated $ 1,147 $ — Foreign exchange forward contracts not designated 4,492 4,800 Total derivatives $ 5,639 $ 4,800 Derivative liabilities reported in Other Current Accrued Liabilities September 27, December 28, (In thousands) Foreign exchange forward contracts designated $ 213 $ 1,472 Foreign exchange forward contracts not designated 1,510 6,752 Total derivatives $ 1,723 $ 8,224 As of September 27, 2015 , the potential effect of rights of set-off associated with the above foreign exchange forward contracts would result in a net derivative asset balance of $4.1 million and an immaterial net derivative liability balance. As of December 28, 2014 , the potential effect of rights of set-off would result in a net derivative asset balance of $2.8 million and a net derivative liability balance of $6.3 million . Effect of Foreign Exchange Forward Contracts Designated as Cash Flow and Net Investment Hedges on the Condensed Consolidated Statements of Operations. All designated cash flow and net investment hedge derivative contracts were considered effective for each of the three and nine months ended September 27, 2015 and September 28, 2014 .

In the first quarter of 2015, due to a decline in revenue from previous forecasts and changes to the product development schedule related to an IPR&D project from the Fusion‑io, Inc. (“ Fusion‑io ”) acquisition, the Company performed impairment tests on the acquisition-related amortizable intangible and IPR&D assets for this acquisition. In the first quarter of 2015, the Company reviewed the forecasts for the Fusion‑io IPR&D project and determined to cancel this project in order to reduce the number of platforms under development, resulting in no future attributable cash flows and a full impairment of the IPR&D asset of $61.0 million was recorded. The project was cancelled and resources were redirected towards the next-generation PCIe and converged enterprise platform. In testing the recoverability of the Fusion‑io acquisition-related amortizable intangible assets, the Company determined that there was no impairment. The impairment test is based upon the lowest level for which identifiable cash flows are available related to the intangible assets. In connection with the impairment analysis in the first quarter of 2015, the Company reduced the expected life of the acquisition-related amortizable developed technology intangible assets from the Fusion‑io acquisition from five years to four years, and will amortize the remaining net carrying amount of this developed technology intangible asset over the next 34 months. As of September 27, 2015 , the net book value of the Fusion‑io acquisition-related amortizable intangible assets was $253.7 million , some or all of which could be subject to impairment. The annual expected amortization expense of intangible assets subject to amortization as of September 27, 2015 was as follows: Acquisition-related Intangible Assets Technology Licenses and Patents (In thousands) Year: 2015 (remaining 3 months) $ 41,553 $ 5,000 2016 126,231 3,333 2017 107,176 — 2018 53,160 — 2019 6,825 — Total intangible assets subject to amortization $ 334,945 $ 8,333

In August 2010 , the Company issued and sold $1.0 billion in aggregate principal amount of 1.5% Convertible Senior Notes due August 15, 2017 (“ 1.5% Notes due 2017 ”) at par. The 1.5% Notes due 2017 may be converted, under certain circumstances, based on an initial conversion rate of 19.0931 shares of common stock per $1,000 principal amount of notes (which represents 19.1 million shares at an initial conversion price of approximately $52.37 per share ). The 1.5% Notes due 2017 contain provisions where the conversion rate and conversion price are adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. Accordingly, as of September 27, 2015 , the conversion rate was adjusted for dividends paid to date to 19.7302 shares of common stock per $1,000 principal amount of notes (which represents 19.7 million shares at a conversion price of approximately $50.68 per share ). The 1.5% Notes due 2017 may be converted at the option of the holders during certain periods as a result of, among other things, fluctuations in the Company’s stock price or in connection with a merger event. Under certain circumstances, the conversion rate will be increased for holders who elect to convert their 1.5% Notes due 2017 in connection with a merger event. The net proceeds to the Company from the sale of the 1.5% Notes due 2017 were $981.0 million . The Company separately accounts for the liability and equity components of the 1.5% Notes due 2017 . The principal amount of the liability component of $706.0 million as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 6.85% , the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. As of the date of issuance, the carrying value of the equity component was $294.0 million . The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 1.5% Notes due 2017 : Three months ended Nine months ended September 27, September 28, September 27, September 28, (In thousands) Contractual interest coupon $ 3,738 $ 3,750 $ 11,214 $ 11,250 Amortization of bond issuance costs 665 667 1,994 2,000 Amortization of bond discount 11,270 10,558 33,348 31,248 Total interest cost recognized $ 15,673 $ 14,975 $ 46,556 $ 44,498 The effective interest rate on the liability component of the 1.5% Notes due 2017 was 6.85% for each of the three and nine months ended September 27, 2015 and September 28, 2014 . The remaining unamortized bond discount of $93.2 million as of September 27, 2015 will be amortized over the remaining life of the 1.5% Notes due 2017 , which is approximately 1.9 years . Convertibility of the 1.5% Notes due 2017 based on the Company’s common stock price is triggered when the stock price exceeds 130% of the conversion price for more than 20 days in the period of 30 consecutive trading days prior to the calendar quarter end, as set forth in the indenture . When the 1.5% Notes due 2017 are convertible, the carrying value is classified as a current liability and the difference between the principal amount payable in cash upon conversion and the carrying value of the equity component of the 1.5% Notes due 2017 is reclassified from Stockholders’ equity to Convertible short-term debt conversion obligation on the Condensed Consolidated Balance Sheet . The determination of whether or not the 1.5% Notes due 2017 are convertible based upon the Company’s stock price is performed on a calendar-quarter basis . The 1.5% Notes due 2017 were convertible during the calendar quarter ended December 31, 2014 , and accordingly, the carrying value of the notes was reported as short-term debt as of December 28, 2014. Based upon the Company’s stock price, the 1.5% Notes due 2017 were not convertible during the calendar quarter ended September 30, 2015 and are not convertible during the calendar quarter ending December 31, 2015, and accordingly, the carrying value of the notes was reported as long-term debt as of September 27, 2015 . Based on the last closing price for the Company’s common stock as of September 27, 2015 of $50.86 , if all of the 1.5% Notes due 2017 then outstanding were converted at the then-current conversion rate, approximately 68 thousand shares would be distributed to the holders. During the three and nine months ended September 27, 2015 , $5 thousand and $73 thousand , respectively, aggregate principal amount of the 1.5% Notes due 2017 (“Converted Notes”) was converted at the holders’ option. During the three and nine months ended September 27, 2015 , with respect to the Converted Notes, the Company delivered cash of $5 thousand and $73 thousand , respectively, for the principal amount, and 10 shares and 515 shares , respectively, of the Company’s common stock with respect to conversion value greater than the principal amount . The Company recorded an immaterial loss during the three and nine months ended September 27, 2015 related to the partial extinguishment of the Converted Notes. The Company pays cash interest at an annual rate of 1.5% , payable semi-annually on February 15 and August 15 of each year, beginning February 15, 2011. Debt issuance costs were $18.7 million , of which $5.5 million was allocated to capital in excess of par value and $13.2 million was allocated to deferred issuance costs and is amortized to interest expense over the term of the 1.5% Notes due 2017 . As of September 27, 2015 , unamortized deferred issuance cost was $3.5 million . Concurrently with the issuance of the 1.5% Notes due 2017 , the Company purchased a convertible bond hedge in which counterparties initially agreed to sell to the Company up to approximately 19.1 million shares of the Company’s common stock, which is the number of shares initially issuable upon conversion of the 1.5% Notes due 2017 in full, at a price of $52.37 per share. The convertible bond hedge agreement contains provisions where the number of shares to be sold under the convertible bond hedge transaction and the conversion price will be adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. Adjusting for dividends paid through September 27, 2015 , the counterparties agreed to sell to the Company up to approximately 19.7 million shares of the Company’s common stock, which is the number of shares issuable upon conversion of the 1.5% Notes due 2017 in full, at a price of $50.68 per share as of September 27, 2015 . This convertible bond hedge transaction will terminate upon the earlier of the maturity date of the 1.5% Notes due 2017 or the first day none of the 1.5% Notes due 2017 remain outstanding due to conversion or otherwise. Settlement of the convertible bond hedge in net shares, based on the number of shares issuable upon conversion of the 1.5% Notes due 2017 , on the maturity date would result in the Company receiving net shares equivalent to the number of shares issuable by the Company upon conversion of the 1.5% Notes due 2017 . Cumulatively through September 27, 2015 , the Company had received 27,134 shares of the Company’s common stock from the exercise of a portion of the convertible bond hedge related to the conversion of $3.3 million aggregate principal amount of the 1.5% Notes due 2017 . In addition, concurrent with the issuance of the 1.5% Notes due 2017 , the Company sold warrants to purchase up to approximately 19.1 million shares of the Company’s common stock at an exercise price of $73.3250 per share. The warrant agreement contains provisions whereby the number of shares to be acquired under the warrants and the strike price are adjusted if the Company pays a cash dividend or makes a distribution to all or substantially all holders of its common stock. Adjusting for dividends paid through September 27, 2015 , holders of the warrants may acquire up to approximately 19.7 million shares of the Company’s common stock at a strike price of $70.9573 per share as of September 27, 2015 . The warrants mature on 40 different dates from November 13, 2017 through January 10, 2018 and are exercisable at the maturity date. At each maturity date, the Company may, at its option, elect to settle the warrants on a net share basis. As of September 27, 2015 , the warrants had not been exercised and remained outstanding. The value of the warrants was initially recorded in equity and continues to be classified as equity. 0.5% Convertible Senior Notes Due 2020. In October 2013 , the Company issued and sold $1.5 billion in aggregate principal amount of 0.5% Convertible Senior Notes due October 15, 2020 (the “ 0.5% Notes due 2020 ”) at par. The 0.5% Notes due 2020 may be converted, under certain circumstances, based on an initial conversion rate of 10.8470 shares of common stock per $1,000 principal amount of notes (which represents 16.3 million shares at an initial conversion price of approximately $92.19 per share). The 0.5% Notes due 2020 contain provisions where the conversion rate and conversion price are adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock. Accordingly, as of September 27, 2015 , the conversion rate was adjusted for dividends in excess of $0.225 per share paid to date to 10.9006 shares of common stock per $1,000 principal amount of notes (which represents 16.4 million shares at a conversion price of approximately $91.74 per share ). The 0.5% Notes due 2020 may be converted at the option of the holders during certain periods as a result of, among other things, fluctuations in the Company’s stock price or in connection with a merger event. Under certain circumstances, the conversion rate will be increased for holders who elect to convert their 0.5% Notes due 2020 in connection with a merger event. The net proceeds to the Company from the sale of the 0.5% Notes due 2020 were approximately $1.48 billion . The Company separately accounts for the liability and equity components of the 0.5% Notes due 2020 . The principal amount of the liability component of $1.15 billion as of the date of issuance was recognized at the present value of its cash flows using a discount rate of 4.43% , the Company’s borrowing rate at the date of the issuance for a similar debt instrument without the conversion feature. As of September 27, 2015 , the carrying value of the equity component of $352.0 million was unchanged from the date of issuance. The following table presents the amount of interest cost recognized relating to the contractual interest coupon, amortization of bond issuance costs and amortization of the bond discount on the liability component of the 0.5% Notes due 2020 : Three months ended Nine months ended September 27, September 28, September 27, September 28, (In thousands) Contractual interest coupon $ 1,875 $ 1,875 $ 5,625 $ 5,625 Amortization of bond issuance costs 627 627 1,882 1,924 Amortization of bond discount 11,433 10,936 34,085 32,334 Total interest cost recognized $ 13,935 $ 13,438 $ 41,592 $ 39,883 The effective interest rate on the liability component of the 0.5% Notes due 2020 was 4.43% for each of the three and nine months ended September 27, 2015 and September 28, 2014 . The remaining unamortized bond discount of $265.8 million as of September 27, 2015 will be amortized over the remaining life of the 0.5% Notes due 2020 , which is approximately 5.1 years . As of September 27, 2015 , the 0.5% Notes due 2020 were not convertible. The Company pays cash interest at an annual rate of 0.5% , payable semi-annually on April 15 and October 15 of each year, beginning April 15, 2014. Debt issuance costs were $17.6 million , of which $4.1 million was allocated to capital in excess of par value and $13.5 million was allocated to deferred issuance costs and is amortized to interest expense over the term of the 0.5% Notes due 2020 . As of September 27, 2015 , unamortized deferred issuance cost was $9.8 million . Concurrently with the issuance of the 0.5% Notes due 2020 , the Company purchased a convertible bond hedge in which counterparties agreed to sell to the Company up to approximately 16.3 million shares of the Company’s common stock, which is the number of shares initially issuable upon conversion of the 0.5% Notes due 2020 in full, at a price of $92.19 per share.

This convertible bond hedge transaction will terminate upon the earlier of the maturity date of the 0.5% Notes due 2020 or the first day none of the 0.5% Notes due 2020 remain outstanding due to conversion or otherwise. As of September 27, 2015 , the Company had not purchased any shares under this convertible bond hedge agreement. Settlement of the convertible bond hedge in net shares, based on the number of shares issuable upon conversion of the 0.5% Notes due 2020 , on the maturity date would result in the Company receiving net shares equivalent to the number of shares issuable by the Company upon conversion of the 0.5% Notes due 2020 . In addition, concurrent with the issuance of the 0.5% Notes due 2020 , the Company sold warrants to purchase up to approximately 16.3 million shares of the Company’s common stock at an exercise price of $122.9220 per share. The warrant agreement contains provisions whereby the number of shares to be acquired under the warrants and the strike price are adjusted if the Company pays a cash dividend greater than a regular quarterly cash dividend of $0.225 per share or makes a distribution to all or substantially all holders of its common stock.

Share-Based Compensation	Share-based Benefit Plans Share-based Plans. The Company has a share-based compensation program that provides its Board of Directors with broad discretion in creating equity incentives for employees, officers, non-employee board members and non-employee service providers. This program includes incentive and non-statutory stock option awards, stock appreciation right awards (“SARs”), restricted stock unit (“RSU”) awards, performance-based cash bonus awards for Section 16 executive officers and an automatic grant program for non-employee board members pursuant to which such individuals receive option grants or other stock awards at designated intervals over their period of board service. These awards are granted under various share incentive plans, all of which are stockholder approved. Stock option awards generally vest as follows: 25% of the shares vest on the first anniversary of the vesting commencement date and the remaining 75% vest proportionately each quarter over the next 12 quarters of continued service. RSU awards generally vest in equal annual installments over a four-year period. Grants to non-employee board members generally vest in one installment on the earlier of (i) the first anniversary of the grant date or (ii) the day immediately preceding the next annual meeting of the Company’s stockholders following the grant date. Additionally, the Company has an Employee Stock Purchase Plan (“ESPP”) that allows employees to purchase shares of common stock at 85% of the fair market value at the subscription date or the date of purchase, whichever is lower. Valuation Assumptions Option Plan Shares . The fair value of the Company’s stock options granted to employees, officers and non-employee board members was estimated using the following weighted-average assumptions: Three months ended Nine months ended September 27, September 28, September 27, September 28, Dividend yield 2.16% 1.14% 1.52% - 2.16% 1.14% - 1.25% Expected volatility 0.33 0.31 0.32 0.32 Risk-free interest rate 1.31% 1.30% 1.19% 1.27% Expected term 4.1 years 4.2 years 4.2 years 4.4 years Estimated annual forfeiture rate 8.20% 8.79% 8.20% 8.79% Weighted-average fair value at grant date $13.92 $21.76 $19.29 $18.84 RSU Plan Shares. The fair value of the Company’s RSU awards granted was based upon the closing price of the Company’s stock price on the date of grant. Employee Stock Purchase Plan Shares . The fair value of shares issued under the Company’s ESPP program was estimated using the following weighted-average assumptions: Three months ended Nine months ended September 27, September 28, September 27, September 28, Dividend yield 2.16% 1.14% 1.52% - 2.16% 1.14% - 1.25% Expected volatility 0.35 0.33 0.35 0.31 Risk-free interest rate 0.24% 0.05% 0.17% 0.07% Expected term ½ year ½ year ½ year ½ year Weighted-average fair value at purchase date $14.10 $22.52 $16.55 $19.39 Share-based Compensation Plan Activities Stock Options and SARs. A summary of stock option and SARs activities under all of the Company’s share-based compensation plans as of September 27, 2015 and changes during the nine months ended September 27, 2015 are presented below: Shares Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Term Aggregate Intrinsic Value (In thousands) (Years) (In thousands) Options and SARs outstanding as of December 28, 2014 4,090 $51.94 4.5 $ 202,044 Granted 998 $81.17 Exercised (505 ) $36.79 $ 18,290 Forfeited (167 ) $65.38 Expired (10 ) $55.33 Options and SARs outstanding as of September 27, 2015 4,406 $59.78 4.4 $ 18,009 Options and SARs vested and expected to vest after September 27, 2015, net of forfeitures 4,195 $58.99 4.3 $ 17,959 Options and SARs exercisable as of September 27, 2015 2,202 $48.80 3.3 $ 16,422 As of September 27, 2015 , the total unrecognized compensation cost related to stock options, net of estimated forfeitures, was approximately $32.2 million , and this amount is expected to be recognized over a weighted-average period of approximately 2.4 years . As of September 27, 2015 , the Company had fully expensed all of its SAR awards. Restricted Stock Units. RSUs are settled in shares of the Company’s common stock upon vesting on a one-for-one basis. Typically, vesting of RSUs is subject to the employee’s continuing service to the Company. The cost of these awards is determined using the fair value of the Company’s common stock on the date of grant, and compensation is recognized on a straight-line basis over the requisite vesting period. A summary of the changes in RSUs outstanding under the Company’s share-based compensation plans during the nine months ended September 27, 2015 is presented below: Shares Weighted-Average Grant Date Fair Value Per Share Aggregate Fair Market Value (1) (In thousands) (In thousands) Non-vested share units as of December 28, 2014 5,587 $67.18 Granted 2,338 $79.41 Vested (1,775 ) $61.92 $ 137,367 Forfeited (644 ) $76.20 Non-vested share units as of September 27, 2015 5,506 $72.98 (1) Aggregate Fair Market Value represents the aggregated market value of RSUs vested during the period as of their individual vest dates. The number of vested RSUs includes shares of common stock that the Company withheld on behalf of employees to satisfy the minimum statutory tax withholding requirements. Total payments for the employees’ tax obligations to taxing authorities are reflected as a financing activity within the Condensed Consolidated Statements of Cash Flows. These net-share settlements had the same effect as share repurchases by the Company as the net share settlements reduced and retired the number of shares that would have otherwise been issued as a result of the vesting. See Note 8 , “ Stock Repurchases .” As of September 27, 2015 , the total unrecognized compensation cost related to RSUs, net of estimated forfeitures, was approximately $280.6 million , and this amount is expected to be recognized over a weighted-average period of approximately 2.6 years . Employee Stock Purchase Plan.

Income Tax Disclosure [Abstract]
Provision for Income Taxes	Provision for Income Taxes The following table presents the provision for income taxes and the effective tax rate: Three months ended Nine months ended September 27, September 28, September 27, September 28, (In thousands, except percentages) Provision for income taxes $ 81,205 $ 110,258 $ 85,968 $ 379,980 Tax rate 37.9 % 29.6 % 25.4 % 32.1 % The provision for income taxes for the three and nine months ended September 27, 2015 prior to discrete items differs from the U.S. statutory tax rate of 35% due primarily to the tax impact of earnings from foreign operations, state taxes, non-deductibility of certain share-based compensation and tax-exempt interest income. Earnings and taxes resulting from foreign operations are largely attributable to the Company’s Chinese, Irish, Israeli, Japanese and Malaysian entities. Earnings in these countries, where tax rates are lower than the U.S. statutory rate, contributed to the majority of the difference between the rate of the Company’s tax provision and the U.S. statutory tax rate. The higher effective tax rate for the three months ended September 27, 2015 compared with the same period in 2014, is primarily related to a benefit recorded as a result of tax audit settlements during the three months ended September 28, 2014 . The lower effective tax rate for the nine months ended September 27, 2015 , compared to the same period in 2014, is primarily attributable to higher tax benefits during the nine months ended September 27, 2015 , resulting from tax audit settlements. As of September 27, 2015 , the Company believes that most of its deferred tax assets are more likely than not to be realized, except for certain loss and credit carry forwards in certain U.S. and foreign tax jurisdictions. As of September 27, 2015 , the Company had not made a provision for U.S. income taxes or foreign withholding taxes on $1.24 billion of undistributed earnings of foreign subsidiaries as the Company intend s to indefinitely reinvest these earnings outside the U.S. to fund its international capital expenditures and operating requirements. The Company determined that it is not practicable to calculate the amount of unrecognized deferred tax liability related to these cumulative unremitted earnings. If these earnings were distributed to the U.S., the Company would be subject to additional U.S. income taxes and foreign withholding taxes reduced by any available foreign tax credits. Unrecognized tax benefits were $98.1 million and $125.2 million as of September 27, 2015 and December 28, 2014 , respectively. Unrecognized tax benefits that would impact the effective tax rate in the future were approximately $74.9 million at September 27, 2015 . Income tax expense for the three and nine months ended September 27, 2015 included expense of $1.2 million of interest and penalties and a benefit of $7.7 million from a reversal of interest and penalties, respectively. Interest and penalties included in income tax expense were immaterial for each of the three and nine months ended September 28, 2014 . It is reasonably possible that the unrecognized tax benefits could decrease by approximately $10.0 million within the next 12 months as a result of the expiration of statutes of limitations and potential settlements of tax authority examinations . The Company is currently under audit by several tax authorities in which the timing of the resolution and/or closure of these audits is highly uncertain . Therefore it is not possible to estimate other changes to the amount of unrecognized tax benefits for positions existing as of September 27, 2015 . The Company is subject to U.S. federal income tax as well as income taxes in multiple state and foreign jurisdictions . During the nine months ended September 27, 2015 , the Company received and signed the closing agreement with the Internal Revenue Service (“IRS”) related to the examination of the Company’s f ederal income tax returns for 2009 through 2011, and finalized audits for certain periods with the California Franchise Tax Board and other various states’ tax authorities . The Company is currently under audit by various state and international tax authorities . The Company cannot reasonably estimate the outcome of these examinations, or provide assurance that the outcome of these examinations will not materially harm the Company’s financial position, results of operations or liquidity . The Company has tax holidays in Malaysia that begin to expire in December 2028 . The impact of the tax holidays was immaterial to all periods presented .

Commitments Contingencies and Guarantees [Abstract]
Commitments, Contingencies and Guarantees	Commitments, Contingencies and Guarantees Flash Ventures Flash Ventures, the Company’s business ventures with Toshiba Corporation (“Toshiba”), consists of three separate legal entities: Flash Partners Ltd., Flash Alliance Ltd. and Flash Forward Ltd. The Company has a 49.9% ownership interest in each of these entities and Toshiba owns 50.1% of each of these entities. Through these ventures, the Company and Toshiba have collaborated in the development and manufacture of NAND flash memory products, which are manufactured by Toshiba at its wafer fabrication facilities located in Yokkaichi, Japan, using semiconductor manufacturing equipment owned or leased by Flash Ventures. The entities within Flash Ventures purchase wafers from Toshiba at cost and then resell those wafers to the Company and Toshiba at cost plus a markup. The Company accounts for its ownership position in each Flash Ventures entity under the equity method of accounting. The Company is committed to purchase its provided three-month forecast of Flash Ventures’ NAND wafer supply, which generally equals 50% of Flash Ventures’ output. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% to 50% of Flash Ventures’ costs to the extent that Flash Ventures’ revenue from wafer sales to the Company and Toshiba are insufficient to cover these costs. Flash Partners. Flash Partners Ltd. (“Flash Partners”) was formed in 2004 . NAND flash memory products provided to the Company by this venture are manufactured by Toshiba primarily at its 300-millimeter wafer fabrication facility (“Fab 3”) located in Yokkaichi, Japan. As of September 27, 2015 , the Company had notes receivable from Flash Partners of $77.9 million , denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Partners with the note proceeds. The Company also has guarantee obligations to Flash Partners; see “ Off-Balance Sheet Liabilities .” As of September 27, 2015 and December 28, 2014 , the Company had an equity investment in Flash Partners of $169.2 million and $167.1 million , respectively, denominated in Japanese yen, adjusted by ($7.7) million and ($7.3) million , respectively, of cumulative translation adjustments recorded in AOCI. Flash Partners’ share of the Fab 3 fabrication facility is fully equipped. Flash Alliance. Flash Alliance Ltd. (“Flash Alliance”) was formed in 2006 . NAND flash memory products provided to the Company by this venture are manufactured by Toshiba primarily at its 300-millimeter wafer fabrication facility (“Fab 4”) located in Yokkaichi, Japan. As of September 27, 2015 , the Company had notes receivable from Flash Alliance of $272.2 million , denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Alliance with the note proceeds. The Company also has guarantee obligations to Flash Alliance; see “ Off-Balance Sheet Liabilities .” As of September 27, 2015 and December 28, 2014 , the Company had an equity investment in Flash Alliance of $251.9 million and $249.5 million , respectively, denominated in Japanese yen, adjusted by ($46.1) million and ($45.5) million , respectively, of cumulative translation adjustments recorded in AOCI. Flash Alliance’s share of the Fab 4 fabrication facility is fully equipped. Flash Forward. Flash Forward Ltd. (“Flash Forward”) was formed in 2010 . NAND flash memory products provided to the Company by this venture are manufactured by Toshiba primarily at its 300-millimeter wafer fabrication facility (“Fab 5”) located in Yokkaichi, Japan. Fab 5 was built in two phases. Phase 1 of Fab 5 is fully equipped. Phase 2 of Fab 5 is partially equipped. Phase 2 is being used for technology transition of the existing Flash Ventures wafer capacity to 1Y‑nanometer and 15‑nanometer technology nodes, wafer capacity expansion and a 3‑dimensional NAND (“ 3D NAND ”) pilot line . An expansion of approximately 5% of Flash Ventures wafer capacity was completed in Fab 5 during the second quarter of 2015 . As of September 27, 2015 , the Company had notes receivable from Flash Forward of $126.4 million , denominated in Japanese yen. These notes are secured by the equipment purchased by Flash Forward with the note proceeds. The Company also has guarantee obligations to Flash Forward; see “ Off-Balance Sheet Liabilities .” As of September 27, 2015 and December 28, 2014 , the Company had an equity investment in Flash Forward of $81.4 million and $79.2 million , respectively, denominated in Japanese yen, adjusted by ($28.6) million and ($28.4) million , respectively, of cumulative translation adjustments recorded in AOCI. New Fab 2. In October 2015, the Company entered into a facility agreement (“ New Fab 2 Agreement ”) with Toshiba related to the construction and operation of Toshiba’s “ New Fab 2 ” fabrication facility, which is primarily intended to provide space to convert a portion of the current Fab 3, Fab 4 and Fab 5 2D NAND capacity to 3D NAND, with expected readiness of the facility in the first calendar quarter of 2016 . Under the New Fab 2 Agreement , the Company is committed to 50% of New Fab 2 ’s start-up costs, as well as 50% of the initial production ramp in New Fab 2 . The Company’s share of the initial commitment is expected to result in equipment investments and start-up costs totaling approximately $600 million , to be incurred primarily through 2016. The Company is also required under the New Fab 2 Agreement to prepay approximately $42 million in October 2015 toward the New Fab 2 building depreciation, to be credited against future wafer charges . Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled. These outstanding purchase commitments are included as part of the total “Noncancelable production purchase commitments” in the “ Contractual Obligations ” table. Off-Balance Sheet Liabilities Flash Ventures. Flash Ventures sells and leases back from a consortium of financial institutions (“lessors”) a portion of its tools and has entered into equipment master lease agreements of which the Company guarantees half of the total outstanding obligations. As of September 27, 2015 , the total amount of the Company’s guarantee obligation of Flash Ventures’ master lease agreements, which reflects future payments and any lease adjustments, was 92.4 billion Japanese yen, or approximately $766 million , based upon the exchange rate at September 27, 2015 . The master lease agreements contain customary covenants for Japanese lease facilities . In addition to containing customary events of default related to Flash Ventures that could result in an acceleration of Flash Ventures’ obligations, the master lease agreements contain an acceleration clause for certain events of default related to the Company as guarantor, including, among other things, the Company’s failure to maintain a minimum stockholders’ equity of at least $1.51 billion . As of September 27, 2015 , the Company’s stockholders’ equity of $5.63 billion was in compliance with the related covenant under Flash Ventures’ master lease agreements . If the Company’s stockholders’ equity were to fall below $1.51 billion , or other events of default occur, Flash Ventures would become non-compliant with certain covenants under its master lease agreements and would be required to negotiate a resolution to the non-compliance to avoid acceleration of the Company’s guarantee obligations under the master lease agreements . Such resolution could include, among other things, supplementary security to be supplied by the Company, as guarantor, or increased interest rates or waiver fees, should the lessors decide they need additional collateral or financial consideration under the circumstances. If a non-compliance event were to occur and if the Company failed to reach a resolution, the Company could be required to pay a portion or the entire outstanding lease obligations covered by its guarantees under such Flash Ventures master lease agreements. The following table details the Company’s portion of the remaining guarantee obligations under each of Flash Ventures’ master lease facilities (both initial and refinanced leases) in both Japanese yen and U.S. dollar-equivalent based upon the exchange rate at September 27, 2015 : Master Lease Agreements by Execution Date Lease Type Lease Amounts Expiration (Japanese yen, in billions) (U.S. dollar, in thousands) Flash Partners: March 2012 Refinanced ¥ 0.4 $ 3,779 2015 March 2014 Initial 3.9 32,181 2019 December 2014 Initial 2.9 24,045 2019 7.2 60,005 Flash Alliance: March 2012 Initial 3.9 32,532 2017 July 2012 Refinanced 7.1 59,195 2017 March 2014 Initial 3.8 31,291 2019 May 2014 Initial 5.0 41,813 2019 August 2014 Initial 5.4 44,599 2019 December 2014 Initial 4.5 37,019 2019 March 2015 Initial 9.5 78,330 2020 June 2015 Initial 7.0 58,007 2020 August 2015 Initial 4.5 37,291 2020 September 2015 Initial 4.0 33,146 2020 54.7 453,223 Flash Forward: November 2011 Initial 5.8 48,247 2016 March 2012 Initial 3.7 30,450 2017 July 2012 Initial 1.5 12,240 2017 December 2014 Initial 4.5 37,291 2019 June 2015 Initial 5.0 41,435 2020 August 2015 Initial 7.5 62,153 2020 September 2015 Initial 2.5 20,717 2020 30.5 252,533 Total guarantee obligations ¥ 92.4 $ 765,761 The following table details the breakdown of the Company’s remaining guarantee obligations between the principal amortization and the purchase option exercise price at the end of the term of the master lease agreements, in annual installments as of September 27, 2015 in U.S. dollars based upon the Japanese yen to U.S. dollar exchange rate at September 27, 2015 : Annual Installments Payment of Principal Amortization Purchase Option Exercise Price at Final Lease Terms Guarantee Amount (In thousands) Year 1 $ 186,838 $ 9,415 $ 196,253 Year 2 153,302 52,309 205,611 Year 3 111,562 32,025 143,587 Year 4 82,368 31,470 113,838 Year 5 44,284 57,482 101,766 Year 6 1,329 3,377 4,706 Total guarantee obligations $ 579,683 $ 186,078 $ 765,761 Guarantees Indemnification Agreements. The Company has agreed to indemnify suppliers and customers for alleged IP infringement. The scope of such indemnity varies, but may, in some instances, include indemnification for damages and expenses, including attorneys’ fees. The Company may periodically engage in litigation as a result of these indemnification obligations. The Company’s insurance policies exclude coverage for third‑party claims for patent infringement. Although the liability is not remote, the nature of the patent infringement indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its suppliers and customers. Historically, the Company has not made any significant indemnification payments under any such agreements. As of September 27, 2015 and December 28, 2014 , no amounts have been accrued in the Condensed Consolidated Financial Statements with respect to these indemnification guarantees. As permitted under Delaware law and the Company’s certificate of incorporation and bylaws, the Company has agreements, or has assumed agreements in connection with its acquisitions, whereby it indemnifies certain of its officers and employees, and each of its directors for certain events or occurrences while the officer, employee or director is, or was, serving at the Company’s or the acquired company’s request in such capacity. The term of the indemnification period is for the officer’s, employee’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is generally unlimited; however, the Company has a Director and Officer insurance policy that may reduce its exposure and enable it to recover all or a portion of any future amounts paid. The Company had no liabilities recorded for these agreements as of September 27, 2015 and December 28, 2014 , as these liabilities are not reasonably estimable even though liabilities under these agreements are not remote. The Company and Toshiba have agreed to mutually contribute to, and indemnify each other and Flash Ventures for, environmental remediation costs or liability resulting from Flash Ventures’ manufacturing operations in certain circumstances. The Company and Toshiba have also entered into patent indemnification agreements under which, in many cases, the Company will share in the expenses associated with the defense and cost of settlement associated with such claims. These agreements provide limited protection for the Company against third‑party claims that NAND flash memory products manufactured and sold by Flash Ventures infringe third‑party patents. The Company has not made any indemnification payments under any such agreements. As of September 27, 2015 and December 28, 2014 , no amounts have been accrued in the Condensed Consolidated Financial Statements with respect to these indemnification guarantees. Contractual Obligations and Off-Balance Sheet Arrangements The following tables summarize the Company’s contractual cash obligations, commitments and off-balance sheet arrangements at September 27, 2015 , and the effect such obligations are expected to have on its liquidity and cash flows in future periods. Contractual Obligations . Contractual cash obligations and commitments as of September 27, 2015 were as follows: Total 1 Year (Remaining 3 months in 2015) 2 - 3 Years (2016 and 2017) 4 - 5 Years (2018 and 2019) More than 5 Years (Beyond 2019) (In thousands) Facility and other operating leases $ 60,487 (4) $ 4,440 $ 25,689 $ 16,078 $ 14,280 Flash Ventures and other related commitments (1) 3,964,269 (4)(5) 339,239 2,108,923 1,035,173 480,934 Convertible senior notes (2) 2,567,867 3,750 1,041,617 15,000 1,507,500 Noncancelable production purchase commitments (3) 248,424 (4) 247,814 610 — — Capital equipment purchase commitments 42,208 38,982 3,226 — — Operating expense commitments 45,874 40,859 5,015 — — Total contractual cash obligations $ 6,929,129 $ 675,084 $ 3,185,080 $ 1,066,251 $ 2,002,714 (1) Includes reimbursement for depreciation and lease payments on owned and committed equipment, funding commitments for loans and equity investments and reimbursement for other committed expenses, including research and development. Funding commitments assume no additional operating lease guarantees; additional operating lease guarantees can reduce funding commitments. (2) Includes principal and interest on both the 1.5% Notes due 2017 and the 0.5% Notes due 2020 . See Note 7 , “ Financing Arrangements .” (3) Includes production purchase commitments to Flash Ventures and other suppliers. (4) Includes amounts denominated in a currency other than the U.S. dollar, which are subject to fluctuation in exchange rates prior to payment and have been translated using the exchange rate at September 27, 2015 . (5) Excludes amounts related to the master lease agreements’ purchase option exercise price at final lease term. The Company has excluded $88.7 million of unrecognized tax benefits (which includes penalties and interest) from the contractual obligation table above due to the uncertainty with respect to the timing of associated future cash flows at September 27, 2015 . The Company is unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities. As discussed previously, if the merger agreement with Western Digital is terminated under specific circumstances, the Company may be required to pay Western Digital up to approximately $553 million . In addition, the merger agreement requires the Company to pay a fee of approximately $184 million if either Western Digital or the Company terminates the merger due to the Company’s stockholders failure to approve this merger.

Related Parties and Strategic Investments	Related Parties and Strategic Investments Flash Ventures with Toshiba. The Company owns 49.9% of each entity within Flash Ventures and accounts for its ownership position under the equity method of accounting. The Company’s obligations with respect to Flash Ventures’ master lease agreements, take-or-pay supply arrangements and R&D cost sharing are described in Note 13 , “ Commitments, Contingencies and Guarantees .” The financial and other support provided by the Company in all periods presented was either contractually required or the result of a joint decision to expand wafer capacity, transition to new technologies or refinance existing equipment lease commitments. Entities within Flash Ventures are variable interest entities (“VIEs”). The Company evaluated whether it is the primary beneficiary of any of the entities within Flash Ventures for all periods presented and determined that it is not the primary beneficiary of any of the entities within Flash Ventures because it does not have a controlling financial interest in any of those entities. In determining whether the Company is the primary beneficiary, the Company analyzed the primary purpose and design of Flash Ventures, the activities that most significantly impact Flash Ventures’ economic performance, and whether the Company had the power to direct those activities. The Company concluded, based upon its 49.9% ownership, the voting structure and the manner in which the day-to-day operations are conducted for each entity within Flash Ventures, that the Company lacked the power to direct most of the activities that most significantly impact the economic performance of each entity within Flash Ventures.

Loss Contingency, Information about Litigation Matters [Abstract]
Litigation	Litigation From time to time, the Company is involved in various litigation matters, including those described below, among others. The litigation proceedings in which the Company is involved from time to time may include matters such as IP, antitrust, commercial, labor, class action and insurance disputes. The semiconductor industry is characterized by significant litigation seeking to enforce patent and other IP rights. The Company has enforced, and likely will continue to enforce, its own IP rights through litigation and related proceedings. In each case listed below where the Company is the defendant, the Company intends to vigorously defend the action. At this time, the Company does not believe it is reasonably possible that losses related to the litigation described below have occurred beyond the amounts, if any, which have been accrued. However, legal discovery and litigation is highly unpredictable and future legal developments may cause current estimates to change in future periods. Ritz Camera Federal Antitrust Class Action. On June 25, 2010, Ritz Camera & Image, LLC (“Ritz”) filed a complaint in the U.S. District Court for the Northern District of California (the “District Court”), alleging that the Company violated federal antitrust law by conspiring to monopolize and monopolizing the market for flash memory products. The lawsuit captioned Ritz Camera & Image, LLC v. SanDisk Corporation, Inc. and Eliyahou Harari, former SanDisk Corporation Chief Executive Officer, purports to be on behalf of direct purchasers of flash memory products sold by the Company and joint ventures controlled by the Company from June 25, 2006 through the present. The complaint alleges that the Company created and maintained a monopoly by fraudulently obtaining patents and using them to restrain competition and by allegedly converting other patents for its competitive use. On February 24, 2011, the District Court issued an Order granting in part and denying in part the Company’s motion to dismiss, which resulted in Dr. Harari being dismissed as a defendant. On September 19, 2011, the Company filed a petition for permission to file an interlocutory appeal in the U.S. Court of Appeals for the Federal Circuit (the “Federal Circuit”) for the portion of the District Court’s Order denying the Company’s motion to dismiss based on Ritz’s lack of standing to pursue Walker Process antitrust claims. On October 27, 2011, the District Court administratively closed the case pending the Federal Circuit’s ruling on the Company’s petition. On November 20, 2012, the Federal Circuit affirmed the District Court’s order denying SanDisk’s motion to dismiss. On December 2, 2012, the Federal Circuit issued its mandate returning the case to the District Court. On July 5, 2013, the District Court granted Ritz’s motion to substitute in Albert Giuliano, the Chapter 7 Trustee of the Ritz bankruptcy estate, as the plaintiff in this case. On October 1, 2013, the District Court granted the Trustee’s motion for leave to file a third amended complaint, which adds CPM Electronics Inc. and E.S.E. Electronics, Inc. as named plaintiffs. On September 19, 2014, the District Court granted the plaintiffs’ motion for leave to file a fourth amended complaint, which adds a cause of action for attempted monopolization and adds MFLASH as a named plaintiff. The plaintiffs filed a motion for class certification, and the Company filed a motion for summary judgment as to all of the plaintiffs’ asserted claims. On May 14, 2015, the District Court granted in part and denied in part plaintiffs’ motion for class certification. On June 22, 2015, the District Court denied the Company’s motion for summary judgment without prejudice to refile its motion once the class notice has been approved and the period for class members to opt out has expired. After the opt-out period expired, the Company renewed its motion for summary judgment, which motion has yet to be heard. Samsung Federal Antitrust Action Against Panasonic and SD ‑ 3C. On July 15, 2010, Samsung Electronics Co., Ltd. (“Samsung”) filed an action in the U.S. District Court for the Northern District of California (the “District Court”) alleging various claims against Panasonic Corporation and Panasonic Corporation of North America (collectively, “Panasonic”) and SD‑3C, LLC (“SD‑3C”) under federal antitrust law pursuant to Sections 1 and 2 of the Sherman Act, and under California antitrust and unfair competition laws relating to the licensing practices and operations of SD‑3C. The complaint seeks an injunction against collection of Secure Digital (“SD”) card royalties, treble damages, restitution, pre- and post-judgment interest, costs, and attorneys’ fees, as well as a declaration that Panasonic and SD‑3C engaged in patent misuse and that the patents subject to such alleged misuse should be held unenforceable. The Company is not named as a defendant in this case, but it established SD‑3C along with Panasonic and Toshiba, and the complaint includes various factual allegations concerning the Company. As a member of SD‑3C, the Company may be responsible for a portion of any monetary award. Other requested relief, including an injunction or declaration of patent misuse, could result in a loss of revenue to the Company. The defendants filed a motion to dismiss on September 24, 2010, and Samsung filed a first amended complaint on October 14, 2010. On August 25, 2011, the District Court dismissed the patent misuse claim with prejudice but gave Samsung leave to amend its other claims. Samsung filed a second amended complaint on September 16, 2011. On January 3, 2012, the District Court granted the defendants’ motion to dismiss Samsung’s complaint without leave to amend. Samsung appealed. On April 4, 2014, the U.S. Court of Appeals for the Ninth Circuit (the “Appeals Court”) issued a decision reversing the District Court’s dismissal on statute of limitations grounds and remanding the case to the District Court for further proceedings. The Appeals Court denied the defendants’ petition for rehearing and issued its mandate to send the case back to the District Court. On November 12, 2014, the defendants filed a petition for writ of certiorari with the U.S. Supreme Court, which the U.S. Supreme Court subsequently denied. Samsung filed a third amended complaint on January 20, 2015. On February 13, 2015, the defendants filed a motion to dismiss, which the District Court granted with respect to certain antitrust allegations, with leave to amend, and with respect to Panasonic’s U.S. subsidiary and denied in all other respects on September 30, 2015. Discovery remains stayed until after completion of the pleading stage. Federal Antitrust Class Action Against SanDisk, et al. On March 15, 2011, a putative class action captioned Oliver v. SD‑3C LLC, et al was filed in the U.S. District Court for the Northern District of California (the “District Court”) on behalf of a nationwide class of indirect purchasers of SD cards alleging various claims against the Company, SD‑3C, LLC (“SD‑3C”), Panasonic Corporation, Panasonic Corporation of North America, Toshiba and Toshiba America Electronic Components, Inc. under federal antitrust law pursuant to Section 1 of the Sherman Act, California antitrust and unfair competition laws, and common law. The complaint seeks an injunction of the challenged conduct, dissolution of “the cooperation agreements, joint ventures and/or cross-licenses alleged herein,” treble damages, restitution, disgorgement, pre- and post-judgment interest, costs, and attorneys’ fees. The plaintiffs allege that the Company (along with the other members of SD‑3C) conspired to artificially inflate the royalty costs associated with manufacturing SD cards in violation of federal and California antitrust and unfair competition laws, which in turn allegedly caused the plaintiffs to pay higher prices for SD cards. The allegations are similar to, and incorporate by reference the complaint in the Samsung Electronics Co., Ltd. v. Panasonic Corporation; Panasonic Corporation of North America; and SD‑3C LLC described above. On May 21, 2012, the District Court granted the defendants’ motion to dismiss the complaint with prejudice. The plaintiffs appealed. On May 14, 2014, the appeals court issued a decision reversing the District Court’s dismissal on statute of limitations grounds and remanding the case to the District Court for further proceedings. The appeals court denied the defendants’ petition for rehearing and issued its mandate to send the case back to the District Court. On December 1, 2014, the defendants filed a petition for writ of certiorari with the U.S. Supreme Court, which the U.S. Supreme Court subsequently denied. On February 3, 2015, the plaintiffs filed a second amended complaint in the District Court. On February 27, 2015, the defendants filed a motion to dismiss, which the District Court granted, with leave to amend, on September 30, 2015. Discovery remains stayed until after completion of the pleading stage. Trade Secret Litigation Against SK Hynix Inc., et al. On March 13, 2014, the Company filed a civil action in Santa Clara Superior Court in California against SK Hynix Inc. (“Hynix”) and certain related entities for trade secret misappropriation arising from the theft of trade secrets by a former employee of the Company and the defendants’ wrongful receipt and use of such information. The lawsuit seeks damages, an injunction and other remedies. Additionally, in March 2014, SanDisk submitted a criminal complaint to the Tokyo Metropolitan Police Department against the former employee. On April 3, 2014, the former employee was indicted by the Tokyo District Public Prosecutor’s Office for theft of trade secrets. The former employee’s criminal trial was held in January 2015. The former employee was convicted and, in March 2015, was sentenced to five years of imprisonment and a fine of 3 million Japanese yen. His appeal of the conviction was dismissed by the Tokyo High Court on September 4, 2015, and he is currently imprisoned. In June 2014, the Company moved for a preliminary injunction requiring Hynix to stop using any of the Company’s information received from the former employee and to return stolen Company material. On July 1, 2014, the court issued a preliminary injunction prohibiting Hynix from using or disclosing trade secret information that originated from materials taken by the former employee and ordering Hynix to provide certain information to the Company’s counsel to facilitate the identification of those documents taken by the former employee that are in Hynix’s possession. The order does not preclude Hynix from continuing to sell NAND flash products that it has already qualified for commercial sale. Hynix filed a notice of appeal of the court’s preliminary injunction and also moved to stay enforcement of the order pending the appeal. On July 16, 2014, the court denied Hynix’s motion with respect to the portion of the order prohibiting use or disclosure of the trade secret information, but granted the motion to stay with respect to the other portion of the order. On November 6, 2014, Hynix removed the case to federal court. On March 26, 2015, the federal court granted the Company’s motion to remand the case to state court and denied Hynix’s motions to compel arbitration and dismiss the case on inconvenient forum grounds. The state court resumed jurisdiction over the case in April 2015. A subsequent motion by Hynix to dismiss the case on inconvenient forum grounds was denied by the court on June 30, 2015. On August 4, 2015, the parties entered into certain confidential agreements pursuant to which they settled the pending trade secret litigation between them, which matters were subsequently dismissed with prejudice. Federal Securities Class Action Against SanDisk et al. Beginning on March 30, 2015, the Company and certain of its officers were named in three putative class action lawsuits filed in the United States District Court for the Northern District of California (Glore v. SanDisk Corp. et al. filed on March 30, 2015; Bowers v. SanDisk Corp. et al. filed on May 6, 2015; City of Sterling Heights General Employees’ Retirement System v. SanDisk Corp. et al. filed on May 27, 2015). Two of the complaints are allegedly brought on behalf of a class of purchasers of the Company’s securities between October 16, 2014 and March 25, 2015, and one is brought on behalf of a purported class of purchasers of the Company’s securities between April 16, 2014 and April 15, 2015. The complaints generally allege violations of federal securities laws arising out of alleged misstatements or omissions by the defendants during the alleged class periods. The complaints seek, among other things, compensatory damages and attorneys’ fees and costs on behalf of the putative classes. On July 9, 2015, the Court consolidated the cases and appointed Union Asset Management Holding AG and KBC Asset Management NV as lead plaintiffs. The lead plaintiffs filed an amended complaint in August 2015. On September 30, 2015, the defendants filed a motion to dismiss, which motion has yet to be heard.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation, Policy	Basis of Presentation. The Company’s fiscal year ends on the Sunday closest to December 31 and its fiscal quarters generally consist of 13 weeks. Fiscal year 2015 will include 53 weeks with 14 weeks in the fourth fiscal quarter, while fiscal year 2014 included 52 weeks. The third quarters of fiscal years 2015 and 2014 ended on September 27, 2015 and September 28, 2014 , respectively. For accounting and disclosure purposes, the exchange rates of 120.67 , 120.44 and 109.23 at September 27, 2015 , December 28, 2014 and September 28, 2014 , respectively, were used to convert Japanese yen to the U.S. dollar. Throughout the Notes to Condensed Consolidated Financial Statements, unless otherwise indicated, references to Net income refer to Net income attributable to common stockholders, references to years or annual periods are references to fiscal years, and references to quarters are references to our fiscal quarters.
Organization and Nature of Operations, Policy	Organization and Nature of Operations. The Company was incorporated in the State of Delaware on June 1, 1988. The Company designs, develops, markets and manufactures data storage solutions in a variety of form factors using its flash memory, controller and firmware technologies. The Company operates in one segment, flash memory storage products.
Consolidation, Policy	Principles of Consolidation. The Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany balances and transactions have been eliminated. Non-controlling interest represents the minority stockholders’ proportionate share of the net assets and results of operations of the Company’s majority-owned subsidiaries. The Condensed Consolidated Financial Statements also include the results of companies acquired by the Company from the date of each acquisition.
Use of Estimates, Policy	Use of Estimates . The preparation of Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. The estimates and judgments affect the reported amounts of assets, liabilities, revenue, expenses and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to customer programs and incentives, product returns, allowance for doubtful accounts, inventories and inventory valuation, valuation and impairments of marketable securities and investments, valuation and impairments of goodwill and long-lived assets, intellectual property (“IP”) claims, income taxes, warranty obligations, restructurings, contingencies, share-based compensation and litigation. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. These estimates form the basis for making judgments about the carrying value of assets and liabilities when those values are not readily apparent from other sources. Actual results could materially differ from these estimates.
Revenue Recognition, Policy	Revenue Recognition, Sales Returns and Allowances and Sales Incentive Programs. The Company recognizes revenue when the earnings process is complete, as evidenced by an agreement with the customer, transfer of title and acceptance, if applicable, pricing is fixed or determinable and collectability is reasonably assured. Revenue is generally recognized at the time of shipment or transfer of title for customers not eligible for price protection and/or a right of return. Sales made to distributors and retailers are generally under agreements allowing price protection and/or a right of return and, therefore, the revenue and related costs of these transactions are deferred until the retailers or distributors sell-through the merchandise to their end customer or their rights of return expire. Estimated sales returns are recorded as a reduction to revenue and deferred revenue and were not material for any period presented in the accompanying Condensed Consolidated Financial Statements. The cost of shipping products to customers is included in cost of revenue. The Company recognizes expenses related to sales commissions in the period in which the commissions are earned. Revenue from patent licensing arrangements is recognized when earned, estimable and realizable. The timing of revenue recognition is dependent on the terms of each license agreement and on the timing of sales of licensed products. The Company generally recognizes royalty revenue when it is reported to the Company by its licensees, which is generally one quarter in arrears from the licensees’ sales of licensed products. For licensing fees that are not determined by the licensees’ sales, the Company generally recognizes license fee revenue on a straight-line basis over the life of the license. Some of the Company’s revenue arrangements are multiple-element arrangements because they are generally comprised of product, software and support services or multiple distinct licenses. For multiple-element arrangements, the Company evaluates whether each deliverable should be accounted for as a separate unit of accounting. For multiple-element arrangements that include support or software elements, the Company analyzes whether tangible products containing software and non-software components function together and therefore should be excluded from industry-specific software revenue recognition guidance. The Company allocates revenue to each element, or the software elements as a group, based on the relative selling price determined in accordance with the Company’s normal pricing and discounting practices for the specific element when sold separately for all multiple-element arrangements. For multiple-element license agreements that include more than one license to distinct technology that are separate units of accounting, the Company allocates revenue to each license based on the relative selling price of each deliverable. License fees related to existing technology with no continuing performance obligations are generally recognized upon license commencement and other license fees are generally recognized straight-line over the life of the license. The Company primarily uses an estimate of selling price to allocate revenue for multiple-element license agreements based upon similar licenses, historical and estimated future sales volume, duration, and market conditions. The Company records estimated reductions of revenue for customer and distributor incentive programs and offerings, including price protection, promotions, co-op advertising and other volume-based incentives and expected returns. All sales incentive programs are recorded as an offset to revenue or deferred revenue. Marketing development programs are recorded as a reduction to revenue.
