    SANTA CLARA, Calif., July 22 /PRNewswire-FirstCall/ -- Integrated Silicon
Solution, Inc. (Nasdaq: ISSI) today reported its financial results for the
third fiscal quarter ended June 30, 2004.

    Revenues in the third quarter of fiscal 2004 were $58.1 million, compared
with $24.3 million in the third quarter of the prior year and $51.5 million in
the quarter ended March 31, 2004.  The Company reported a net profit for the
June 2004 quarter of $5.6 million or $0.15 per share on a diluted share basis.
This compares to a net loss for the June 2003 quarter of ($5.9) million or
($0.21) per share and a net profit in the recent March 2004 quarter of
$12.5 million, or $0.34 per share on a diluted share basis.  The profit for
the March 2004 quarter included $8.7 million or $0.24 per diluted share for a
pre-tax gain on the Company's sale of a portion of its stock held in SMIC.

    "Quarter to quarter, our June 2004 revenue is 13% growth over March 2004,
and our revenue growth over the June 2003 quarter is 139%," said Jimmy Lee,
ISSI's Chairman and CEO. "We are seeing some increase in orders for our SRAM
products from the networking and telecom markets, and we believe that, with
both Christmas and Chinese New Year on the horizon, the consumer electronics
markets for our DRAM will see good growth."
