          ISSI Announces Fourth Quarter and Fiscal Year 2004 Results

    SANTA CLARA, Calif., Oct. 28 /PRNewswire-FirstCall/ -- Integrated Silicon
Solution, Inc. (Nasdaq: ISSI) today reported its preliminary financial results
for the fourth fiscal quarter and year ended September 30, 2004.
    Revenue in the fourth quarter was $31.1 million, compared with $30.0
million in the prior year period.  The Company reported a net loss for the
fourth quarter of ($15.6) million or ($0.43) per diluted share, compared with
a net loss of ($2.5) million or ($0.09) per diluted share, in the prior year
period.  The September quarter loss of ($15.6) million includes a charge for
inventory write downs of $12.1 million.
   For the fiscal year ended September 30, 2004, revenue totaled $181.0
million compared to $97.7 million for fiscal year 2003, or 85% growth.  The
net profit for the year ended September 30, 2004 totaled $3.5 million or $0.10
per diluted share compared to a net loss of ($28.1) million or ($1.01) per
diluted share in fiscal year 2003.
    The Company ended the 2004 fiscal year with cash and cash equivalents of
$139.0 million and no long or short-term debt obligations.
    "Following a period of shortages and product allocation in the first half
of the year, we experienced the results of too much inventory build up in the
channels and a high inventory level at certain customers. The result was that,
for the September 2004 quarter, our DRAM family saw average selling prices
drop by about 36% from the June quarter, and overall unit shipments also
declined," said Jimmy Lee, ISSI's chief executive officer.  "This resulted in
disappointing operating results for the September 2004 quarter.  Our balance
sheet remains strong and we will work diligently to expand our revenue and to
leverage off our subsidiaries in Asia to reduce operating costs."
    The statement of operations for the year ended September 30, 2004
currently includes an estimated tax provision of $488K.  The company is still
analyzing the utilization of its tax loss carry forwards in light of certain
possible carry forward restrictions in Section 382 of the federal tax code.
If this analysis results in a conclusion that the company's tax loss carry
forwards are restricted, then the tax provision for the quarter and year ended
September 30, 2004 could be increased by a material amount when the company
reports its audited results for the year.

    Certain statements in this news release may be considered forward-looking
statements, including statements related to working diligently to expand

gross profit margin, changes in demand for the Company's products or the
products in which the Company's products are used, changes in market
conditions, inability to expand revenue, inability to effectively reduce
expenses, inability to add new products or diversify product lines, order
cancellations, and order rescheduling, product warranty claims, competition,
the level and value of inventory held by OEM customers or the Company, the
Company's ability to secure manufacturing capacity from its foundries, or
other factors.  Further information that could affect the Company's results is
