Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements

Note 1

Description of Transaction

On July 17, 2009, Integrated Device Technology, Inc. (“IDT” or the “Company”) completed the sale of certain assets related to its network search engine business (the “NWD Assets”) to NetLogic Microsystems, Inc. (“NetLogic” and together with IDT, the “Parties”), pursuant to an Asset Purchase Agreement by and between the Company and NetLogic dated April 30, 2009 (the “Agreement”). Upon closing of the transaction, NetLogic paid the Company $100 million in cash consideration, which included inventory valued at approximately $10 million (subject to adjustment) and assumed specified liabilities related to these assets. The Company’s NWD Assets are part of the Communication reportable segment.

Upon closing of the transaction, the Parties entered into an Intellectual Property Cross-License Agreement (the “Cross-License Agreement”) pursuant to which IDT granted to NetLogic and certain of its affiliates a license to use certain of IDT’s retained technology assets in connection with the NWD Assets in certain fields of use. In addition, NetLogic and its affiliates granted back to IDT and its affiliates a license to use certain of the technology assets included in the NWD Assets in certain fields of use. The licenses granted in the Cross-License Agreement are royalty-free and irrevocable.

In connection with the closing of the transaction, IDT entered into a noncompetition agreement with NetLogic related to the NWD Assets for a term of three years, subject to certain exceptions. In addition, the Company will provide certain transitional services and supplies to NetLogic for a limited time following the closing of the sale. Additional details regarding the transaction are provided in the related Current Report on Form 8-K previously filed by the Company on April 30, 2009 and Current Report on Form 8-K previously filed by the Company on May 6, 2009.

Note 2

Pro Forma Adjustments

The accompanying unaudited pro forma condensed consolidated financial statements have been prepared to illustrate the effect of the sale of the disposed NWD Assets on the Company’s historical results of operations and financial position. The accompanying unaudited pro forma condensed consolidated statements of operations and consolidated balance sheet are represented as if the transaction described in Note 1 had occurred on April 1, 2008 (the beginning of fiscal 2009). The unaudited pro forma condensed consolidated balance sheet is presented as if the transaction had occurred on March 29, 2009 (the end of fiscal 2009). The actual effect of the sale could differ from the pro forma adjustments presented here. However, management believes that the assumptions used and the adjustments made are reasonable under the circumstances and given the information available.

These unaudited pro forma condensed consolidated financial statements are presented for illustrative purpose only and not necessarily indicative of the operating results or the financial position that would have been achieved had the sale been consummated as of the dates indicated or of the results that may be obtained in the future. These unaudited pro forma condensed consolidated financial statements and accompanying notes should be read together with the Company’s audited consolidated financial statements and accompanying notes as of and for the year ended March 29, 2009, and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s Annual Report on Form 10-K for the year ended March 29, 2009.

The pro forma adjustments are as follows:

a. To eliminate the revenues, cost of revenues and operating expenses which the Company believes are directly attributable to the disposed NWD Assets.

b. To record the cash consideration received from NetLogic.

c. To eliminate the inventory sold to NetLogic.

d. To eliminate the photomask sets transferred to NetLogic.

e. To eliminate the goodwill relating to the NWD Assets in accordance with Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets.”

f. To accrue for the estimated transaction costs associated with the sale and record short term portion of estimated deferred gain associated with the supply agreement with NetLogic.

g. To record the long term portion of estimated deferred gain associated with the supply agreement with NetLogic.

h. To record the preliminary gain on sale of NWD Assets as if the transaction had consummated on March 29, 2009:
