        This Amendment No. 1 amends and supplements the Registration Statement on Form 8-A filed by Monolithic System Technology, Inc.

Item 1.    Description of Registrant's Securities to be Registered.

Item 1 of the Form 8-A is amended and supplemented by adding the following:

        On February 23, 2004, the Board of Directors of the Company authorized and adopted a First Amendment (the "First Amendment") to Rights Agreement, entered into between the Company and Wells Fargo Bank, N.A., the stock transfer agent of the Company. The First Amendment amended the Rights Agreement (the "Rights Agreement") entered into between the Company and Wells Fargo Bank, N.A. on October 11, 2000. Furthermore, on December 14, 2004, the Board of Directors of the Company authorized and adopted a Second Amendment (the "Second Amendment") to Rights Agreement.

        The purpose of the First Amendment was to prevent Synopsys, Inc. ("Synopsis"), Mountain Acquisition Sub, Inc., a wholly owned subsidiary of Synopsis, and any of their respective Affiliates or Associates (as each such term is defined in the Rights Agreement) from triggering the Rights (as defined in the Rights Agreement) in connection with the proposed acquisition of the Company by Synopsis. By its terms, the First Amendment ceased to be effective upon termination of the Agreement and Plan of Merger and Reorganization dated as of February 23, 2004 among Synopsis, Mountain Acquisition Sub, Inc. and the Company, which termination occurred effective as of April 16, 2004.

        The purpose of the Second Amendment is to enable Ingalls & Snyder LLC ("I&S"), a registered broker dealer and investment advisor, to acquire common stock of the Company exceeding the 15% limitation on beneficial ownership under the Rights Agreement so long as such shares of common stock are not acquired or held with the purpose or effect of changing or influencing control of the Company, or in connection with or as a participant in any transaction having such purpose or effect. This exclusion is limited to shares of common stock as to which I&S brokerage account managers share dispositive power, have only non-discretionary voting power and have no direct or indirect pecuniary interest. Any single account holder or retail customer of I&S, and any single broker at I&S with respect to such broker's personal trading account, shall remain subject to the 15% limitation on beneficial ownership contained in the Rights Agreement.
