Rambus XDR(TM) Memory Architecture Named 2008 DesignVision Winner

Rambus Inc. (NASDAQ:RMBS), one of the world´s premier technology
licensing companies specializing in high-speed memory architectures,
is pleased to announce that the International Engineering Consortium
(IEC) has chosen the Rambus XDR(TM) memory architecture as the winner
in the 2008 DesignVision Awards category for Semiconductors and ICs
(IP). The IEC DesignVision Awards recognize technologies,
applications, products, and services judged to be the most unique and
beneficial to the industry.

"This year´s winners exemplify the highest level of innovation in
today´s industry," commented IEC Executive Vice President Roger
Plummer. "We are pleased to congratulate Rambus for its XDR memory
architecture, which received the 2008 DesignVision Award this week at
DesignCon 2008."

"We take great pride in advancing the state-of-the-art in
innovative memory architectures and are honored to be recognized by
the IEC," said Kevin Donnelly, senior vice president of Engineering at
Rambus. "The XDR architecture is a total memory system solution that
enables blazing fast speeds with the fewest devices, making it ideal
for computing and consumer electronics applications."

Rambus recently announced that Toshiba has taken a license for the
XDR memory architecture for its next-generation HDTV chipsets. In
addition, Qimonda has begun shipping its first samples of XDR DRAM,
and Elpida has begun shipping 4.8GHz XDR memory, the world´s fastest
production DRAM.

Key components enabling the breakthrough performance of the XDR
memory architecture are:

-- The XDR DRAM, a high-speed memory IC that turbo-charges
standard CMOS DRAM cores with a high-speed interface capable
of 4.0 GHz data rates providing up to 8 GB/s of bandwidth with
a single device.

-- The XIO controller IO cell providing the same high-speed
signaling capability found on the DRAM, but adding additional
enhancements like FlexPhase(TM) technology that optimizes
timing and eliminates the need for trace length matching.

-- The XMC memory controller, a fully synthesizable logical
memory controller that is optimized to take advantage of
innovations like Dynamic Point-to-Point which provides for
capacity expansion while delivering the signal integrity
benefits of point-to-point signaling.

-- The XCG clock generator providing the system clocks with four
programmable outputs, guaranteed to meet the clocking
requirements for the XIO and XDR DRAM devices.
