LOS ALTOS, Calif., Feb 08, 2010 (BUSINESS WIRE) -- Rambus Inc. (NASDAQ:RMBS), one of the world's premier technology
licensing companies, today unveiled its Mobile XDR(TM) memory architecture
for next-generation mobile products. Based on innovations from Rambus'
groundbreaking Mobile Memory Initiative introduced last year, Mobile XDR
memory offers a high-bandwidth, low-power memory architecture to enable
devices that exceed the power and performance targets for
next-generation mobile products.
"Future mobile applications demand far higher performance and longer
battery life than today's mobile products can achieve," said Sharon
Holt, senior vice president of Licensing and Marketing at Rambus.
"Mobile XDR memory provides the ideal solution for designers to offer
leading-edge mobile content in a dramatically lower power and
cost-effective manner. Uniquely, the Mobile XDR architecture delivers
these benefits in SoC and DRAM devices that can be built with current
manufacturing infrastructure reducing both risk and time-to-market."
The Mobile XDR memory architecture will enable future mobile memory
platforms which can achieve throughputs of up to 4.3Gbps per pin with
unequaled power efficiency. With this breakthrough performance, SoC
platforms can achieve over 17GB/s of memory bandwidth from a single
Mobile XDR DRAM device while extending the battery life of many mobile
products by more than 30 minutes, when operating under the most
power-hungry usage profiles.
The Mobile XDR architecture enables significant cost savings for SoC
chips by offering pin-count reduction and a smaller interface. Power
reduction is achieved through an aggressive decrease in active power
coupled with fast transition times to power-saving modes. This enables
system designers to minimize memory subsystem power to increase battery
life across a wide range of applications from simple voice transmission
to demanding multimedia such as stereoscopic 3D HD video.
Mobile XDR memory architecture uses key innovations from Rambus' Mobile
Memory Initiative:
-
Very Low-Swing Differential Signaling (VLSD): a bi-directional,
ground-referenced, differential signaling technology which offers a
high-performance, low-power and cost-effective solution for
applications requiring extraordinary bandwidth and superior power
efficiency.
-
FlexClocking(TM) Architecture: utilizes asymmetric partitioning and
places critical calibration and timing circuitry in the SoC interface,
greatly simplifying the design of the DRAM interface.
-
Advanced Power State Management (APSM): Reduces memory system power
and provides ultra-fast transition times between various low-power and
active operating modes.
In addition, Rambus' FlexPhase(TM) and Microthreading technologies help
enable the superior power efficiency of the Mobile XDR architecture.
Key components of the Mobile XDR memory architecture include Mobile XDR
DRAM, Mobile XDR memory controller PHY (MIO), and the Mobile XDR memory
controller (MXC). The Mobile XDR memory architecture is currently
available for licensing. For additional information, please visit www.rambus.com/mobile.
