             ISSI ANNOUNCES SECOND QUARTER FISCAL YEAR 2006 RESULTS

         Santa Clara, Calif.--April 25, 2006--Integrated Silicon Solution, Inc.
(Nasdaq: ISSI) today reported its financial results for the second fiscal
quarter ended March 31, 2006.

         Revenue in the second fiscal quarter ending March 31, 2006 was $53.2
million, compared with $51.1 million in the December 2005 quarter and $35.7
million in the March 2005 quarter. The reported net loss for the March 2006
quarter of ($3.7) million or ($0.10) per diluted share includes a $5.8 million
inventory write-down, a $1.56 million charge for FAS 123R stock option expense,
a $0.3 million charge for a write-down of in-process technology as a result of
acquiring additional shares of ICSI, and a $2.7 million gain related to the sale
of investments and assets. These results compare with a net loss for the March
2005 quarter of $13.8 million or ($0.38) per share on a diluted share basis
which included an inventory write-down of $1.3 million, a charge of $1.1 million
against the Company's facility lease, and a charge of $9.3 million for the
equity interest in ICSI in Taiwan prior to our acquisition.

         "Revenue grew 4% in the March 2006 quarter from the previous quarter
and 49% over the same period last year." said Jimmy Lee, ISSI's Chairman and
CEO. "The year to year revenue growth shows the benefit of our ICSI acquisition.
Additionally, we exited the Bluetooth and Flash Controller markets which will
reduce our total expenses, but resulted in an inventory write-down. We remain
optimistic about our ability to grow in niche market segments such as automotive
markets and DRAM die business which we expect will help to enhance our gross
margins."

Safe Harbor Statement
- ---------------------

         The statements in this press release regarding exiting markets,
reducing our total expenses, and being optimistic about our ability to grow in
niche markets and our expectations regarding enhanced gross margins are
forward-looking statements that are subject to risks. Our actual results may
differ materially from current expectations due to many factors, including
supply and demand conditions in the market place, unexpected reductions in
average selling prices, our ability to sell our products for the die business
and automotive applications and the pricing and gross margins achieved on such
sales, our ability to retain the revenue and customers of ICSI, our ability to
control or reduce operating expenses, changes in manufacturing yields, order
cancellations, order rescheduling, product warranty claims, competition, the
level and value of inventory held by OEM customers, or other factors.
Furthermore, the purchase accounting and valuation information in this release
regarding the acquisition of additional shares of ICSI are preliminary and are
subject to further review by the Company, its advisors, and its auditors. The
valuation numbers could be changed as a result of further review.

         Stockholders of ISSI are cautioned not to place undue reliance on our
forward-looking statements, which speak only as of the date such statements are
made. ISSI does not undertake any obligation to publicly update any
forward-looking statements to reflect events, circumstances, or new information
after this April 25, 2006 press release, or to reflect the occurrence of
unanticipated events. Further information that could affect the Company's
results is detailed in ISSI's periodic filings with the Securities and Exchange
Commission, including its report on Form 10Q for the quarter ended December 31,
2005.
