FOR IMMEDIATE RELEASE

ISSI ANNOUNCES THIRD QUARTER FISCAL YEAR 2007 RESULTS

      San Jose Calif.--July 26, 2007--Integrated Silicon Solution, Inc. (Nasdaq:
ISSI) today  reported its financial  results for the third fiscal  quarter ended
June 30, 2007.

      Revenue  in the  third  fiscal  quarter  ending  June 30,  2007 was  $59.9
million, compared with $60.0 million in the March 2007 quarter and $53.2 million
in the June 2006 quarter.  The reported net profit for the June 2007 quarter was
$4.9 million,  or $0.13 per diluted  share,  with gross  margins of 19.6%.  This
profit includes a $2.3 million gain on sale of investments,  a $2.3 million gain
in connection with the settlement of a commercial dispute, a $0.9 million charge
for FAS 123R stock  option  expense,  and a $0.9  million  expense for legal and
accounting  fees for the recently  completed  restatement of our prior financial
results.  These  results  compare  with a net loss for the June 2006  quarter of
($6.9) million,  or ($0.18) per share on a diluted share basis, which included a
$4.9 million  inventory  write-down and a $0.9 million charge for FAS 123R stock
option expense.

      The Company's cash, cash  equivalents and short-term  investments  totaled
$126.1 million at June 30, 2007 which was an increase of $4.6 million from March
31, 2007. This increase was primarily due to operating results and from sales of
investment  securities.  The Company's  inventory at June 30, 2007 totaled $40.5
million which was a reduction of $15.1 million from the quarter ending March 31,
2007.

      "Despite soft pricing this  quarter,  we were able to meet our revenue and
margin expectations and deliver solid financial results. We are pleased with the
significant  inventory  reduction  and a 12.5%  growth in revenue  from the same
quarter in 2006," said Jimmy Lee, ISSI's Chairman and CEO.
