Rambus Announces IBM to License Multi-Protocol SerDes



    Rambus Inc. (NASDAQ:RMBS), one of the world´s premier technology
    licensing companies specializing in high-speed memory architectures

    today announced that IBM has licensed Rambus´ multi-protocol SerDes
    (Serial/Deserializer) cell designed for advanced networking, server
    and general ASIC applications. This sophisticated multi-protocol
    SerDes cell provides IBM with a high-performance and low-power
    solution for implementation on its 45nm silicon-on-insulator (SOI)
    technology.

    "The SerDes requirements for ASICs and servers are increasingly
    demanding and cover many protocols," said Steve Longoria, vice
    president for Semiconductor Solutions, IBM. "Rambus´ multi-protocol
    SerDes solution gives us a flexible, single IP solution that
    simplifies the design process without compromising performance, power
    or silicon die area."

    The Rambus multi-protocol SerDes is a single IP cell leveraging a
    scalable architecture that offers data rates of 1.25 Gbps to 6.4 Gbps.
    It features an advanced Rambus phase-locked loop (PLL) architecture

    which achieves low jitter over a wide variety of operating data rates
    and enables best-in-class performance in a small silicon die area.

    "Our customers are faced with design challenges that call for both
    high performance and low power in order to meet their application
    requirements," said Sharon Holt, senior vice president of Worldwide
    Sales, Licensing and Marketing at Rambus. "IBM is renowned for its
    advanced technology, and we are pleased to provide our innovative
    multi-protocol SerDes for its ASIC library and product offerings."

    The Rambus SerDes solution also incorporates the Rambus
    LabStation(TM) characterization environment, enabling thorough
    qualification, advanced testability features, and improved
    time-to-market.
