  ITEM 5.         OTHER EVENTS
  
        (a)       On November 2, 1998, Quality Semiconductor, Inc. (the
  "Registrant") and Integrated Device Technology, Inc. ("IDT") jointly announced
                                                         ---                    
  the execution of an Agreement and Plan of Merger (the "Merger Agreement")
  pursuant to which a wholly-owned subsidiary of IDT will be merged with and into
  the Registrant (the "Merger").  Consummation of the Merger is subject to certain
  closing conditions, including approval by the Registrant's shareholders and
  regulatory approval.
  
                  Pursuant to the Merger Agreement each outstanding share of
  Common Stock of the Registrant will be exchanged for 0.6875 shares of Common
  Stock of IDT in a tax-free stock-for-stock exchange. This ratio was determined
  by arms-length negotiations among the parties. It is anticipated that the
  combination will be accounted for as a pooling of interest. The parties intend
  to file a registration statement on Form S-4 under the Securities Act of 1933,
  as amended to register the shares issued to the Registrant's shareholders in
  the merger. A copy of the press release is attached hereto as Exhibit 99 and
  is incorporated herein by reference.
