Rambus Unveils New Innovations for Main Memory

Rambus Inc., one of the world's premier technology licensing companies specializing in high-speed memory architectures, today unveiled a set of innovations that can advance computing main memory beyond current DDR3 data rate limits to 3200Mbps. These innovations, available for licensing, build on Rambus’ award-winning designs and include patented and patent pending technologies. Through this collection of innovations, designers can achieve higher memory data rates, higher effective throughput, better power efficiency and the increased capacity necessary for future computing applications.

"Product advancements in multi-core computing, virtualization and chip integration put ever-increasing demands on the memory sub-system, a key performance limiter in today’s performance computing systems," said Craig Hampel, Rambus Fellow. "This collection of breakthrough innovations from Rambus allows for memory systems that are better suited for the bandwidth and workloads of these throughput-oriented multi-core processors, increasing the design and solution space for future main memory to enable a new generation of computing platforms."

The Rambus key innovations to advance the main memory roadmap include:
  • FlexPhase Technology - introduced in the XDR memory architecture, can enable higher data rates compared to direct strobing technology used in DDR3;
  • Near Ground Signaling - supports high performance at greatly reduced IO power, allowing operation at 0.5V while still maintaining robust signal integrity;
  • FlexClocking Architecture - introduced in Rambus’ Mobile Memory Initiative, reduces clocking power by eliminating the need for a DLL or PLL on the DRAM;
  • Module Threading - increases memory efficiency and reduces DRAM core power, and when combined with Near Ground Signaling and FlexClocking technology, can cut total memory system power by over 40%;
  • Dynamic Point-to-Point (DPP) - provides a path for capacity upgrades without compromising performance through robust point-to-point signaling.
Rambus licenses its broad portfolio of patented innovations for use in its leadership and industry-standard chip interface solutions, as well as industry defined interfaces.Source: Rambus

All good news, lets hope these tricks make it to the sales shelf one day.

Lets face it just about EVERY memory researcher is forever publishing amazing new innovations, and we are still stuck with DDR3 that depending on your configuration can perform WORSE than DDR2...

Since they are 240Pin DDR3, they probably wont be like RDIMMs

RDIMM = Registered DIMM, you mean RIMM, Rambus Inline Memory Module.

As for Rambus getting a place in PC's, I doubt it. I can't imagine any CPU/chipset manufacturer going for it after last time. Unless of course Rambus could work wthout specific platform support, ie all logic being on the memory module and being able to work with normal memory controllers.

you do know if rambus carried on we would have much MUCH faster ram then we do now. :rolleyes:

People DID steal there technology, but instead of rambus just suing and carrying on designing more they just cried about it, when they had nifty things of there own it was just slightly higher priced.

Memory was always good, just cost too much,, I hope they keep the price down this time around. if they get a this time.

And so what if we had faster RAM?
Performance of system RAM in PCs has the smallest impact on performance compared to any other component.

Actually, RAMBUS willingly gave away their IP back then when DDR-SDRAM standard was being designed and RAMBUS still was a member in JEDEC. Then they left JEDEC as their own ignorance/malevolent bait 'n' trap tactic they misinterpreted JEDEC's member rules that don't allow "area-of-effect royalties". Then they somehow expect the industry should stop using the stuff they gave away? The best part is they've apparently managed to enforce their view and royalties via tech-illiterate courts that think DDR signaling is some brilliant engineering feat worthy being called as "IP".
:slap:

RAMBUS "invented" such mundane things as double data rate I/O, eg. Like, they invented the bloody wheel and demand royalty for all things that have them.
