    MoSys Providing Memory for Wii

    It's 1T-SRAM again, but they don't say how much.


    MoSys' 1T-SRAM(R) Embedded Memory Technology Enables Nintendo's Next
    Leap in Video Games; High Performance, High Density 1T-SRAM Powers
    Upcoming Wii Home Game Console

    SUNNYVALE, Calif.--(BUSINESS WIRE)--June 19, 2006--MoSys, Inc., the
    industry's leading provider of high-density system-on-chip (SoC)
    embedded memory solutions, today announced that Nintendo's upcoming
    Wii(TM) video game console uses MoSys' patented 1T-SRAM technology to
    implement the very high performance memory within the Wii console's
    graphics system.

    This is the latest result from the more than six-years-long technical
    collaboration between the two companies. Previous generations of MoSys'
    1T-SRAM technology were incorporated in Nintendo's earlier game
    console, the Nintendo GameCube(TM), in 1999, and shipped in
    multi-million quantities. The newest 1T-SRAM implementations embedded
    within the Wii console are fabricated using NEC Electronics' advanced
    90nm CMOS-compatible embedded DRAM process technology. These high speed
    and ultra low latency memories are used as the main embedded memory on
    the graphics chip and in an additional external memory chip.

    "We are pleased that Nintendo has again chosen our 1T-SRAM to power
    their latest generation game console," said Chet Silvestri, chief
    executive officer at MoSys, Inc.

    "Designing the Wii console required an incredible list of breakthroughs
    in technology and innovation. The performance delivered by MoSys'
    1T-SRAM technology is an important element of our solution," said Genyo
    Takeda, Senior Managing Director, General Manager, Integrated Research
    & Development Division at Nintendo. "The graphic performance of Wii
    benefits from MoSys' ability to develop highly innovative and
    dependable embedded memory products."

    About 1T-SRAM

    Available in densities up to 600Mbits, MoSys' patented 1T-SRAM
    technology represents the most advanced embedded memory technology in
    the world. It 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 fifth 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 across
    multiple silicon processing generations and supported by a wide number
    of pure-play wafer foundries and independent Device Manufactures
    (IDMs).

    in the press release you'll note that they said previous generation
    MoSys 1T-SRAM was incorporated into Gamecube in 1999.

    some of you might say, "WTF Gamecube came out in 2001". Well just so
    you know, the Flipper GPU was designed largely in 1999. that is when
    Nintendo, ArtX, collaborating with MoSys and NEC, embedded 1T-SRAM
    into Gamecube's Flipper GPU.

    Ultimately, 1T-SRAM became Gamecube's main system memory as well.

    from what is known, a newer generation of 1T-SRAM has been embedded
    into the Wii's ATI-designed 'Hollywood' GPU, and 1T-SRAM is also, the
    main memory once again. 24 MB + 64 MB of external memory. That's not
    counting what is embedded into the GPU.
