ITEM 1. SECURITY AND ISSUER:

            This statement on Schedule 13D relates to shares of common stock,
$0.001 par value per share of Integrated Device Technology, Inc., a Delaware
corporation (the "Issuer") acquired by private investment funds managed by Perry
Corp. (the "Shares"). The principal executive offices of the Issuer are located
at 2975 Stender Way, San Jose, California, 95054.

ITEM 2. IDENTITY AND BACKGROUND:

            This statement on Schedule 13D is filed on behalf of Perry Corp., a
New York corporation, and Richard C. Perry, an American citizen. Perry Corp. is
a registered investment adviser that provides asset management services to
private investment funds. Richard C. Perry is the President, sole director, and
sole stockholder of Perry Corp. The address of Perry Corp. and Richard C. Perry
is 767 Fifth Avenue, New York, NY 10153. A joint filing agreement of Perry Corp.
and Richard C. Perry is attached hereto as Exhibit A.

            The names, citizenship, business addresses and principal occupations
of each of the directors and executive officers of Perry Corp. (other than
Richard C. Perry) are set forth in Schedule A, which is incorporated herein by
reference.

            During the last five years, neither Perry Corp., Richard C. Perry,
nor any of the persons listed in Schedule A has been convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or has been a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION:

            The Shares were acquired by two or more private investment funds for
which Perry Corp. acts as a general partner and/or investment adviser. The
source of funds for the purchase transactions was the working capital of such
investment funds. The total purchase price for the Shares was $72,716,943.

ITEM 4. PURPOSE OF TRANSACTION:

            The Shares were acquired in the ordinary course of business by two
or more private investment funds managed by Perry Corp. The transactions were
open market transactions. This amendment to Schedule 13D is being filed as a
result of the press release on the Event Date reporting the merger (the
"Merger") between the issuer and a party unrelated to Perry Corp. As a result of
the Merger, the percentage interest of the outstanding shares of common stock of
the Issuer held by the reporting person fell below five percent. Except as
otherwise described herein, none of Perry Corp., Richard C. Perry or the persons
listed on Schedule A have any current plans or proposals which relate to or
would result in any of the transactions or changes contemplated in Items 4(a)
through 4(j) of Schedule 13D.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER:

            (a)-(b) Perry Corp. is the indirect beneficial owner of 6,728,000
Shares, which constitutes approximately 3.38% of the Issuer's outstanding
shares. Perry Corp. has sole power to vote and sole power to dispose of the
6,728,000 Shares. By virtue of his position as President and sole stockholder of
Perry Corp., Richard C. Perry may be considered to indirectly beneficially own
such Shares.

            (c) See Exhibit B attached hereto. The transactions set forth on
Exhibit B were made by private investment funds for which Perry Corp. acts as a
general partner and/or investment adviser since the filing of the original
Schedule 13D on September 9, 2005. All of the transactions set forth in Exhibit
B were purchases and were effected either in ordinary brokerage transactions or
via electronic communications networks.

            (d) The limited partners of (or investors in) each of two or more
private investment funds for which Perry Corp. acts as general partner and/or
investment adviser have the right to participate in the receipt of dividends
from, or proceeds from the sale of, the Shares held for the accounts of their
respective funds in accordance with their respective limited partnership
interests (or investment percentages) in their respective funds.

            (e) As of the Event Date the reporting person ceased to be the
beneficial owner of more than five percent of the outstanding shares of common
stock of the Issuer.



ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
        SECURITIES OF THE ISSUER:

            Except for the arrangements described in Item 5(d) above, to the
best knowledge of Perry Corp., there are no contracts, arrangements,
understandings or relationships (legal or otherwise) between the persons
enumerated in Item 2 and any other person with respect to any securities of the
Issuer, including but not limited to, transfer or voting of any of the Shares,
finder's fees, joint ventures, loan or option arrangements, puts or calls,
guarantees of profits, division of profits or loss, or the giving or withholding
of proxies.

ITEM 7. MATERIALS TO BE FILED AS EXHIBITS

      Exhibit A --      Agreement between Perry Corp. and Richard C. Perry to
                        file this statement jointly on behalf of each of them.

      Exhibit B --      List of transactions in the Issuer's common stock since
                        the filing of the original Schedule 13D on September 9,
                        2005.

      Schedule A --     Executive Officers and Directors of Perry Corp. (other
                        than Richard C. Perry).



                                    SIGNATURE

      After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
