Qimonda and Rambus Sign Technology License for XDR(TM) DRAM

Rambus Inc. (Nasdaq:RMBS), one of the world's premier technology
licensing companies specializing in high-speed chip interfaces, today
announced that Qimonda AG, a leading global producer of DRAM memory
products, recently signed a technology license agreement for the
Rambus XDR(TM) memory interface solution. The Rambus XDR solution will
be implemented in Qimonda's 75nm process technology for integration
into high-volume applications, including game consoles, digital
televisions, set-top boxes and PC graphics.

"Since signing a patent license agreement with Qimonda, we have
worked towards a relationship where our engineering teams could
collaborate on leadership memory solutions to serve the global
market," said Sharon Holt, senior vice president of Worldwide Sales,
Licensing and Marketing at Rambus. "We are very proud to be working
with Qimonda to deliver this advanced memory product for a growing
number of applications in computing and digital entertainment."

"The XDR memory solution completes our broad graphics RAM
portfolio to better serve high-performance and high-bandwidth
applications for the fast growing global computing and consumer
electronics markets," said Robert Feurle, vice president and general
manager of Graphics DRAM at Qimonda.

Rambus XDR DRAM, as part of the XDR memory architecture, achieves
an order of magnitude higher performance than today's standard
memories. Perfect for graphics processing, consumer electronics,
network, and server applications, a single, 2-byte wide, 3.2 GHz XDR
DRAM component provides 6.4 GB/sec of peak bandwidth, and enables PCB
savings and cost savings by utilizing the fewest number of ICs.

The advanced XDR memory architecture features key enabling
technologies built on patented Rambus innovations, including:

-- Differential Rambus Signaling Level (DRSL), a low-voltage,
low-power, differential signaling standard that enables
scalable multi-GHz, bi-directional, and point-to-point data
busses that connect an XDR memory controller (XIO) to XDR DRAM
devices;

-- Octal Data Rate (ODR), a technology that transfers eight bits
of data on each clock cycle, four times as many as today's
state-of-the-art memory technologies that use DDR (Double Data
Rate) clocking;

-- FlexPhase(TM), a circuit technology that enables flexible
phase relationships between signals, allowing precise on-chip
alignment of data with clock; and

-- Dynamic-Point-to-Point (DPP), an innovation that maintains the
signal integrity benefits of point-to-point signaling on the
data bus, while providing the flexibility of capacity
expansions with module upgrades. DPP was recognized with a
"2005 Innovation of the Year" award by industry publication
EDN Magazine.
