Advances differential memory signaling to 20Gpbs and single-ended
memory signaling to 12.8Gbps
SUNNYVALE, Calif.--(BUSINESS WIRE)--
Rambus Inc. (NASDAQ:RMBS), one of the world's premier technology
licensing companies, today announced it has advanced differential
signaling for SoC-to-memory interfaces to a groundbreaking 20 gigabits
per second (Gbps) and developed innovations which can extend
single-ended memory signaling to an unparalleled 12.8Gbps. Rambus has
also developed innovations which enable a seamless transition for memory
architectures from single-ended to differential signaling as data rates
rise to meet the performance requirements of future-generation graphics
and gaming systems. Rambus will demonstrate its breakthroughs in memory
signaling technology this week at DesignCon 2011.
The latest technology advancements of Rambus' Terabyte
Bandwidth Initiative enable unmatched power efficiency and
compatibility to single-ended memory architectures, including GDDR5 and
DDR3. With the addition of FlexMode™ interface technology, a
multi-modal, SoC memory interface PHY, supporting both differential and
single-ended signaling, can be implemented in a single SoC package
design with no additional pins. Rambus has achieved a power efficiency
of 6 milliwatts (mW) per Gbps when operating at 20Gbps in a 40nm-process
silicon test vehicle. These innovations address critical system
challenges to extending signaling rates by addressing power efficiency
and compatibility needs.
"We have paved multiple paths for the industry by providing solutions
that extend single-ended signaling beyond today's limits and developing
the means for a seamless transition to differential signaling," said
Sharon Holt, senior vice president and general manager of the
Semiconductor Business Group at Rambus. "By advancing data rates in an
extremely power-efficient way, and enabling compatibility to current
industry-standard memories, we have removed the technical and business
barriers for customers to achieve unprecedented capabilities in their
products."
Graphics cards and game consoles are the marquee performance products
for consumers. The demand for photorealistic game play, 3D images, and a
richer end-user experience is constantly pushing system and memory
requirements higher. Today's high-end graphics processors support as
much as 128 gigabytes per second (GB/s) of memory bandwidth, and future
generations will push memory bandwidth to upwards of one terabyte per
second (TB/s).
Through the Terabyte Bandwidth Initiative, Rambus has developed key
innovations using its renowned signaling and memory architecture
expertise. These Rambus patented innovations include Fully Differential
Memory Architecture (FDMA), FlexLink™ C/A and 32X data rate. The latest
addition to these innovations, FlexMode interface technology, enables
support of both differential and single-ended memory interfaces in a
single SoC package design. FlexMode technology achieves this with no
additional pins through programmable assignment of signaling I/Os to
either data or command/address.
Launched in November 2007, the Terabyte Bandwidth Initiative reflects
Rambus' ongoing commitment to innovation in cutting-edge performance
memory architectures. The initiative serves as the foundation for future
memory architectures that offer increased performance, higher and
scalable data bandwidth, area optimization, enhanced signal integrity,
and multi-modal capability for gaming, graphics and multi-core computing
applications.
