Rambus Inc., the innovative technology solutions company that brings invention to market, today announced its first LPDDR3 offering targeted at the mobile industry. In the Rambus R+ solution set, the R+ LPDDR3 memory architecture is fully compatible with industry standards while providing improved power and performance. This allows customers to differentiate their products in a cost-effective manner with improved time-to-market. Further helping improve design and development cycles, the R+ LPDDR3 is also available with Rambus' collaborative design and integration services.

The R+ LPDDR3 architecture includes both a controller and a DRAM interface and can reduce active memory system power by up to 25% and supports data rates of up to 3200 megabits per second (Mbps), which is double the performance of existing LPDDR3 technologies. These improvements to power efficiency and performance enable longer battery life and enhanced mobile device functionality for streaming HD video, gaming and data-intensive apps.

"Each generation of mobile devices demands even higher performance with lower power. The R+ LPDDR3 technology enables the mobile market to use our controller and DRAM solutions to provide unprecedented levels of performance, with a significant power savings," said Kevin Donnelly, senior vice president and general manager of the Memory and Interface Division at Rambus. "Since this technology is a part of our R+ platform, beyond the improvements in power and performance, we're also maintaining compatibility with today's standards to ensure our customers have all the benefits of the Rambus' superior technology with reduced adoption risk."

The seed to the improved power and performance offered by the R+ LPDDR3 architecture is a low-swing implementation of the Rambus Near Ground Signaling technology. Essentially, this single-ended, ground-terminated signaling technology allows devices to achieve higher data rates with significantly reduced IO power. The R+ LPDDR3 architecture is built from ground up to be backward compatible with LPDDR3 supporting same protocol, power states and existing package definitions and system environments.

Additional key features of the R+ LPDDR3 include:
  • 1600 to 3200 Mbps data rates
  • Multi-modal support for LPDDR2, LPDDR3 and R+ LPDDR3
  • DFI 3.1 and JEDEC LPDDR3 standards compliant
  • Supports package-on-package and discrete packaging types
  • Includes LabStation software environment for bring-up, characterization, and validation in end-user application
  • Silicon proven design in GLOBALFOUNDRIES 28 nm-SLP process
The R+ LPDDR3 memory controller and DRAM interface solutions are currently available. For additional information on the Rambus R+ LPDDR3, visit this page.

I wish this "company" would go under already. Everytime I see their name in a press release it makes my skin crawl. Slimy crooks.

aka patent trolls




Lol finally they make something useful

I see this every time Rambus is mentioned, yet, no one seems to think that the companies Rambus sues are stupid for not checking patents to begin with?:shadedshu

Any company with staff lazy enough to get caught out by Rambus deserves it.

The issue with the US patent office is that they grant some really ridiculous patents. It wouldn't be unusual for two patents filed by two individual entities to be nearly identical with a slight deviation in method or mechanism. Other times, patents granted can be vague or overly broad. It may be more difficult and time consuming (greater opportunity cost) to comb through all existing patents pertaining to the technology versus simply crossing fingers and praying that nothing is being infringed.

I'm talking out of my ass here so forgive me if I'm wrong.

Something being too hard, or time consuming, is no excuse. You must always face the consequences of your actions...or lack of action, as the case may be.

If a firm's risk assessment of the situation shows that it's more beneficial to forgo the extra research and maximize profit, they'll do it. It's not uncommon, similar to how Ford opted to assume the possibility of lawsuit payouts rather than recall a particular lineup of cars in the 1900s because they figured it would be cheaper to pay legal penalties for the small percentage of customers who would be affected by their faulty cars than to have to repair each and every single unit produced. It's not so much that it's more difficult or time consuming, but that it's more costly.

Again, talking out of my ass here, but this is what I learned in intro to economics in high school and microeconomics in college.

I think the prevailing sentiment is that any company who sets out to hide their IP with intent to ambush companies, to destroy evidence when they know it will be germane to a litigation suit doesn't paint them in a favourable light. You might want to note that the percentage of suits that Rambus brings versus their actual wins is pretty damn low.
LSI, STMicro and MediaTek for example.

You could also argue that even in cases that they win, the price they pay tends to outweigh any remuneration - the invalidation of the Barth patents for instance that Rambus had previously used to "win" judgements.

No, I do not work for Rambus. That's just what occurs to me every time I see people complain about Rambus. Clearly, by this news post, they are still developing technology of some sorts, and aren't just patent trolls, contrary to most posts complaining that they are only that.

And if the patent system is broke, and Rambus capitalized on that, well, good for them. Kinda how the economy works...they aren't the problem, just a result of the problem. which makes it all just "meh" situation to me.

Oh gods this is a pit of pure hatred you're treading into. People call Apple patent trolls, Rambus is like a Patent Troll God to these people. Also soon they will come with arguments about corporate greed and morals and the ruination of everything.

This would explain so much if it was about discussing technology patents.

Oh yes, even here in the "jungle" everybody knows that except Apple, Rambus are the biggest patent trolls ever. No doubt about it.
