ISSI Announces 2Gb DDR2 SDRAM

SAN JOSE, Calif., Aug. 3, 2011 (GLOBE NEWSWIRE) -- Integrated Silicon Solution,
Inc. (Nasdaq:ISSI), a leader in advanced memory solutions, today announced it
has begun sampling production units of its new 2 Gigabit (2Gb) DDR2 device, the
newest addition to their family of DDR2 SDRAMs. The first device is the
IS43DR16128, which is organized as 128Mx16 and packaged in an 84-ball BGA. This
on-going expansion of the DDR2 SDRAM product family adds to ISSI's extensive
offering of DRAMs, and by using advanced technology, ISSI is able to provide the
long-term product support required by long lifecycle applications in automotive,
communications, medical, and industrial application.

The new device is available with clock speeds up to 333MHz (DDR2-667). In
addition to the 2Gb device, ISSI also offers 1Gb, 512Mb and 256Mb DDR2 devices
in commercial, industrial, and automotive temperature grades. The 256Mb density
includes x32, x16, and x8 organizations, while the 512Mb and 1Gb densities
include x16 and x8 organizations. The DDR2 DRAM product family operates from a
single supply voltage of 1.8V.

"Our automotive customers are excited by our expanding portfolio of high-density
DRAMs and our long-term commitment. Customers have begun to qualify the new 2Gb
DDR2 device in vehicle infotainment systems, where the integration of new
features is driving memory demand," said Lyn Zastrow, vice president of the
Automotive Business Unit.

"The mobile data explosion is driving memory density requirements in mobile
infrastructure products, such as base stations. Additionally these applications
have long-life requirements, so long-term support of 2Gb DDR2 products is key
for our customers in that space," said Pat Lasserre, director of the
Communications Business Unit. Key applications in communications include access
and aggregation nodes, routers and switches, network storage, optical transport,
and base stations. Other applications include medical instrumentation, energy
meters, and security systems.

In addition to SDR, mobile SDR/DDR, DDR, and DDR2 SDRAMs, ISSI also offers a
complete line of both asynchronous and synchronous SRAM with densities from 64Kb
to 72Mb. ISSI also has a range of Known Good Die (KGD) memories in its
portfolio.

Availability

Samples of the IS43DR16128 in both commercial and industrial temperature ranges,
and the IS46DR16128 in automotive temperature ranges are available now with
volume production shipments beginning in Q4, 2011.
