ISSI Announces 512Mb SDR and DDR MOBILE DRAMs

SAN JOSE, Calif., June 14, 2011 (GLOBE NEWSWIRE) -- Integrated Silicon Solution,
Inc. (Nasdaq:ISSI), a leader in advanced memory solutions, today announced the
addition of four new products to their low-power mobile DRAM portfolio. These
1.8V mobile 512Mb DRAMs are available in SDR (Single Data Rate) or DDR (Double
Data Rate), and in 32Mx16, or 16Mx32 configurations with DDR speeds up to
333Mbps per data line. These additions to the mobile DRAM product family now,
using advanced technology, enables ISSI to provide the long-term product support
required by long lifecycle applications in automotive, medical, industrial and
mobile communications.

Mobile DRAMs are used in a variety of applications including automotive
telematics and safety, portable medical imaging and analysis equipment, smart
phones, and smart meters. These mobile products use JEDEC standard 1.8V supply
and I/O levels, and they feature power-saving features like
temperature-compensated self-refresh (TCSR), partial array self-refresh (PASR),
deep power down, and adjustable driver strength.

"The new 512Mb mobile SDR and 512Mb mobile DDR products are important additions
to our DRAM portfolio of products as many automotive customers are looking for
power-saving features in our DRAMs," said Lyn Zastrow, ISSI vice president of
the Automotive Business Unit. "These products are used in variety of automotive
applications including audio and camera functions. They are available with an
operating temperature range of -40 degrees C to 105 degrees C, which is an added
benefit that many customers have been asking for ISSI to support."

"A number of applications in the industrial and medical market are currently
adopting mobile SDR and mobile DDR products," said Sean Long, director of
marketing, industrial/medical/military & die products for ISSI. "Our long-term
support and a broad selection of 16Mb to 512Mb mobile solutions from ISSI are
instrumental factors to gain design wins in a variety of applications including
smart meters and portable medical equipment."

The 32Mx16 SDR (IS42VM16320D) is available in a 54-ball BGA package, and the
32Mx16 DDR (IS43LR16320B) is available in a 60-ball BGA package. The 16Mx32 SDR
(IS42VM32160D) and the DDR (IS43LR32160B) are available in a 90-ball BGA
package. Temperature ranges offered are 0 degrees C to 70 degrees C, -40 degrees
C to 85 degrees C, and -40 degrees C to 105 degrees C. These new 512Mb devices
add to a complete line of mobile DRAMs from ISSI now covering densities from
16Mb to 512Mb.

In addition to the mobile SDR and DDR SDRAM product families, ISSI also offers
high speed SDR, DDR, and DDR2 SDRAM product families in a variety of densities,
organizations, and temperature ranges as well as a complete line of SRAMs
targeted for automotive, communications, industrial, medical, military and
consumer applications.
