Technology-First Delivers New Standard For Graphics
Performance

LONDON, England (September 6, 1999)— Nintendo and MoSys
today announced that MoSys’ patented 1T-SRAM technology will be
used in the next Nintendo home game console to embed large very
high performance memories directly onto the system’s graphics chip,
being developed by ArtX, Inc. Embedded 1T-SRAM represents the most
advanced memory technology in the world, and will eliminate transmission
times between memory and chip allowing a new industry standard for
graphics performance.

The multi-year licensing agreement announced at the ECTS show in
London culminates nearly one year of technical collaboration between
the two companies. The embedding of these very large Static Random
Access Memory (SRAM) blocks to enable exceptional performance is
an industry-first for graphics chips. Game players can expect more
detailed graphics moving at higher frame rates. Use of the single
transistor 1T-SRAM technology allows embedding of even more SRAM
than is used to achieve performance on leading edge CPUs such as
the PowerPC™ or Pentium® III.

“Simply stated, the incredible performance of MoSys 1T-SRAM
memory with the proprietary custom graphics chip designed by ArtX
is the perfect match for IBM’s custom, copper-based CPU,” says
Howard Lincoln, chairman, Nintendo of America Inc. “We will
employ this technology to surpass the game experience offered by
any competing console or personal computer.”

“We are convinced the use of such a large amount of this ultra
high performance memory will put this graphics processor in a league
of its own,” says Dr. Fu-Chieh Hsu, chairman, CEO and president
of MoSys. “Nintendo’s use of our 1T-SRAM uniquely meets the
blinding performance and easy manufacturability requirements of
next-generation cost-conscious consumer products, and is an excellent
flagship application for our technology.”

“Nintendo promises to set a new standard for graphics by using
the unique capabilities of embedded 1T-SRAM technology to deliver
graphics memory performance that is dramatically faster than competitive
DRAM-based systems”, said Bob Merritt, senior analyst at Semico
Research Corp. “Consequently, MoSys’ 1T-SRAM allows the performance,
previously only possible in small cache memories, to be available
in this consumer graphics system.”

ABOUT 1T-SRAM

Available in densities up to 128Mbits, MoSys’ patented 1T-SRAM
technology uses a single transistor cell to achieve its exceptional
density while maintaining the refresh-free interface and low latency
random memory access cycle time associated with traditional six-transistor
SRAM cells. Embedded 1T-SRAM allows designers to get beyond the
density limits of six-transistor SRAMs; it also reduces much of
the circuit complexity and extra cost associated with using embedded
DRAM. 1T-SRAM memories can be fabricated in either pure logic or
embedded memory processes using as little as one ninth of the area
of traditional six-transistor SRAM cores. In addition to the exceptional
performance and density, this technology offers dramatic power consumption
savings by using only a quarter of the power of traditional SRAM
memories. 1T-SRAM technology is volume production proven in millions
of MoSys’ discrete memory devices.
