Rambus Unveils Next Generation XDR(TM) Memory Interface; 8GHz XDR2 DRAM with Micro-Threading Enables Unprecedented Graphics Capabilities
TOKYO—(BUSINESS WIRE)—July 7, 2005—
Rambus Inc. (Nasdaq:RMBS), one of the world's premier
technology licensing companies specializing in high-speed chip
interfaces, today announced the latest version of its high-bandwidth
XDR memory interface technology, named XDR(TM)2. The XDR2 memory
interface uses a micro-threaded DRAM core and circuit enhancements
that enable data rates starting at 8GHz, making it five times faster
than today's best-in-class GDDR graphics DRAM products.
Building on the high-performance XDR memory interface technology,
the XDR2 memory interface is targeting applications that require
extreme memory bandwidth, such as 3D graphics, advanced video imaging,
and network routing and switching applications. In order to achieve
high bandwidth efficiency and data rates of 8GHz and beyond the XDR2
memory interface incorporates:
-- Micro-threading -- a DRAM core innovation developed to
increase memory system efficiency to enable DRAMs to provide
more usable data bandwidth to requesting memory controllers,
while minimizing power consumption;
-- Adaptive Timing -- a speed enhancement to today's XDR
FlexPhase(TM) timing circuits that compensates for process,
voltage and temperature variations during real-time operation;
-- Transmit Equalization -- an output circuit that minimizes the
adverse system effects of reflections and attenuation that
typically limit the speed of DRAM systems;
-- DRSL Signaling -- a 200mV differential signaling standard that
provides superior common mode noise rejection with an on-chip
terminated point-to-point topology that minimizes reflections
and reduced signal transition times associated with device
loading and PCB trace stubs.
"We are continually pushing interface technology forward to
develop compelling and innovative solutions that meet our customers'
needs," said Laura Stark, vice president of the Platform Solutions
Group at Rambus. "XDR2 is our latest iteration of the XDR DRAM
architecture and will help 3D games and graphics-intensive
applications realize the high performance potential that users
demand."
Rambus engineers work closely with chip and system companies to
optimize the DRAM controllers to take advantage of the performance
benefits that the XDR2 solution provides. The XDR2 memory interface is
available for licensing now and could be shipping in products by 2007.
Technical specifications are available from Rambus upon request. For
