Rambus, a designer of various memory and interface technologies, has announced the development of a fast power-on, low-power clocking technology that can enable a whole new class of memory devices. The new technology enables 5Gb/s+ data transfer speeds with minimal power consumption.

“Through this work, we’ve dramatically reduced system complexity and have saved substantial power while increasing performance to more than 5Gb/s per differential link. When incorporated into an SoC-to-memory interface, or SoC-to-SoC link, this development can significantly reduce the memory system power and time-to-first access, driving us closer to the vision of energy proportional computing,” said Jared Zerbe, technical director at Rambus.

Implemented in a 40nm low-power CMOS process, this technology is capable of transitioning from a zero-power idle state to a 5Gb/s+ data transfer rate in 5ns while achieving active power of only 2.4mW/Gb/s.

In order to improve the energy efficiency of servers and mobile systems, system designers are continually looking for ways to reduce the energy required by the memory subsystem. Memories typically used in today’s server applications are challenged to cycle in and out of the lowest power operating state rapidly. In mobile systems, which support a wide range of power modes, low power operation is usually accomplished through use of complex power state circuits. With this approach, developed by Rambus Labs, a feed-forward architecture is used to achieve extremely fast turn-on and turn-off, simplifying the system design and significantly reducing the overall system power requirements.

Sadly the only reason I see them developing this, or anything for that matter, is for revenues from patent infringement.

Rambus basically scouts out promising and/or obvious technology trends, then rushes to develop a "solution" that can be as broadly patented as possible. Thus it can lay out it's "patent traps" as effectively as possible.

All it takes is a few big players to "pay up" to keep funding the beast.

I wonder how many lawyers Rambus hired before announcing this patent.
