Toshiba Licenses Rambus XDR(TM) Memory Architecture For HDTV Chipset

Rambus Inc. (Nasdaq:RMBS), one of the world´s premier technology
licensing companies specializing in high-speed memory architectures,
today announced that Toshiba Corporation has licensed its XDR(TM)
memory controller interface cell (XIO) and XDR memory controller (XMC)
for next-generation high-definition television (HDTV) chipsets. The
XIO and XMC will be implemented in Toshiba´s 65nm process. Operating
at 4.8Gbps, the XDR memory architecture will allow Toshiba´s HDTV
chipset to deliver state-of-the-art image processing performance in
its customers´ HDTVs.

"HDTVs now require as much memory bandwidth as many PCs in order
to deliver the advanced features consumers demand," said Hideki
Moriyama, Deputy General Manager of the System LSI Division at
Toshiba´s Semiconductor Company. "With the XDR memory architecture, we
are able to achieve both superior performance and a reduced bill of
materials for our customers´ HDTV applications."

The XDR memory architecture uses patented Rambus innovations such
as Octal Data Rate (ODR) technology, Differential Rambus Signaling
Level (DRSL), and FlexPhase(TM) circuits to deliver the highest
bandwidth available while using fewer DRAM devices than
industry-standard memory solutions. Higher memory performance as
delivered by the XDR architecture enables the advanced features of
next-generation HDTVs such as 1080p+ resolution, 120Hz refresh rates,
12-bit color, multiple full HD Picture-in-Picture (PiP) data streams,
and advanced image enhancement algorithms.

"As a leading supplier of chipsets to HDTV manufacturers Toshiba
delivers an exceptional viewing experience for consumers," said Sharon
Holt, senior vice president of sales, licensing and marketing at
Rambus Inc. "With the XDR memory architecture, we´re able to meet the
growing demands for bandwidth in an exciting new generation of
consumer electronics products."

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. XDR DRAM licensees
include Elpida Memory Inc., Qimonda AG, and Samsung Electronics Co.
Ltd. For more information about the XDR memory architecture, as well
as the next-generation XDR2 DRAM with micro-threading, please visit
