Rambus XDR(TM) Memory Architecture Adopted in Texas Instruments DLP Projector System


    Rambus Inc. (Nasdaq:RMBS), one of the world's premier technology
    licensing companies specializing in high-speed chip architectures,
    today announced that its XDR(TM) memory architecture has been adopted
    in Texas Instruments Incorporated (TI) (NYSE:TXN) DLP(R) technology.
    Projectors powered by the DLP chip utilizing the XDR memory
    architecture provide unmatched image quality and stunning color, and
    are ideal for displaying movies, sports, games or digital photos.

    "The XDR memory architecture and its innovative technologies are
    key enablers of the razor-sharp images and excellent reproduction of
    fast-motion video made possible by the advanced DLP chip
    architecture," said Lars Yoder, vice president and manager, Front
    Projection Business Unit, DLP Products, Texas Instruments
    Incorporated. "The Rambus engineering teams supported us with complete
    services from design through production helping us make a new
    generation of amazing DLP projectors a reality."

    The DLP chip with its millions of microscopic mirrors and the
    sophisticated electronics that surround it, including the Rambus XDR
    memory architecture, deliver a stunning viewing experience. The XDR
    memory architecture operating at 4.0GHz with a single, 2-byte wide XDR
    DRAM provides an unmatched 8.0 GB/s of peak memory bandwidth. The
    Rambus XDR DRAM, XDR Memory Controller (XMC), XDR IO Cell (XIO), and
    XDR Clock Generator (XCG) work together seamlessly to provide the
    unprecedented levels of memory performance required to generate the
    precise, lifelike images rich with color, contrast and brightness
    delivered by DLP technology.

    "TI's DLP technology sets the standard with compelling images
    demanded by both consumers and businesses," said Sharon Holt, senior
    vice president of worldwide sales, licensing and marketing at Rambus
    Inc. "Rambus and Texas Instruments have a long history of
    collaboration on leading-edge DLP solutions, and we are very proud to
    continue our focus on designing and delivering advanced technology
    that enriches the end-user experience."

    The XDR memory architecture features key enabling technologies
    built on patented Rambus innovations that include low-voltage,
    low-power Differential Rambus Signaling Level (DRSL); Octal Data Rate
    (ODR) technology that transfers eight bits of data on each clock
    cycle; FlexPhase(TM) circuit technology for precise on-chip alignment
    of data with clock; and Dynamic-Point-to-Point (DPP) for
    point-to-point signaling on the data bus.

    Proven in high-volume and cost-competitive applications, Rambus
    solutions are backed by comprehensive engineering support services
    that range from chip design to system integration, and can scale for
    future cost reduction. For more information on the XDR memory
    architecture, as well as the next generation of XDR, the 8GHz XDR2
    DRAM with micro-threading, please visit www.rambus.com/xdr. XDR DRAM
