              ISSI ANNOUNCES FIRST QUARTER FISCAL YEAR 2006 RESULTS

    SANTA CLARA, Calif., Jan. 30 /PRNewswire-FirstCall/ -- Integrated Silicon
Solution, Inc. (Nasdaq: ISSI) today reported its financial results for the
first fiscal quarter ended December 31, 2005.

    Revenue in the first fiscal quarter ending December 31, 2005 was $51.1
million, compared with $61.5 million in the September 2005 quarter and $30.6
million in the December 2004 quarter. The reported net loss of ($3.7) million or
($0.10) per diluted share includes a $3.6 million inventory write-down, a $1.0
million charge for FAS 123R stock option expense, and a $0.2 million charge for
a write-down of in-process technology as a result of acquiring additional shares
of ICSI. These results compare with a net loss for the December 2004 quarter of
$13.3 million or ($0.37) per share on a diluted share basis which included an
inventory write-down of $9.6 million or ($0.26) per share.

    "We did see a drop in our DRAM average selling prices during the December
quarter," said Jimmy Lee, ISSI's Chairman and CEO. "This hurt the revenue line.
However, December 2005 quarterly revenue was 67% greater than December 2004
quarterly revenue as a result of our acquisition of ICSI. We are very pleased
with how the acquisition is going and believe we are well-positioned for the
future."

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
