FOR IMMEDIATE RELEASE

ISSI ANNOUNCES SELECTED FINANCIAL RESULTS FOR FISCAL SECOND QUARTER

      San Jose, Calif.--May 2, 2007--Integrated  Silicon Solution, Inc. (Nasdaq:
ISSI) today reported  selected  financial  results for the second fiscal quarter
ended March 31, 2007.

      Revenue in the quarter ending March 31, 2007 was $60.0  million,  compared
with $62.1  million  reported in the December  2006 quarter and $53.2 million in
the March 2006 quarter. This represents a decline of 3.4% from the December 2006
quarter, and a 12.8% increase from the same period in the previous year.

      The Company's cash, cash  equivalents and short-term  investments  totaled
$121.5  million at March 31, 2007 which was an increase  of $12.1  million  from
December 31, 2006.  This  increase was  primarily  due to proceeds from sales of
investment  securities.  The Company's inventory at March 31, 2007 totaled $55.6
million which was flat with the quarter ending December 31, 2006.

      "Demand for memories in our target  markets was flat this  quarter,  while
DRAM price  declines  capped a  challenging  quarter"  said  Jimmy  Lee,  ISSI's
Chairman  and CEO.  "We are pleased  with only a slight drop in revenue from the
prior quarter, and strong growth over the same period a year ago."

      Due to the  continuing  internal  investigation  of its past stock  option
granting  practices by the Special  Committee of the Board of Directors  and the
pending restatement of the Company's past financial results,  the Company is not
providing detailed GAAP or Non-GAAP financial information for the fiscal quarter
ended March 31, 2007.  The Company  intends to issue full results for the fiscal
quarter  ended  March  31,  2007,  and to file  its Form  10-Q for that  period,
together  with  any  restated  historical  financial  statements,   as  soon  as
practicable  after  completion  of the  restatement.  The Company  was  recently
advised,  as expected,  that the Securities and Exchange Commission has issued a
nonpublic formal order of private investigation in connection with its review of
the Company's historical stock option granting practices.
