Qimonda starts volume production of Rambus XDR DRAM for PS3

200°
325w ago - Qimonda, the second largest DRAM company worldwide, has announced that they are mass producing XDR RAM modules for use in the PlayStation 3. An article on EDN.com is suggesting that Qimonda might be mass producing 512mb XDR RAM modules that they first showed off earlier this year. Current models of the Playstation 3 offer only 256mb of XDR RAM, which some gamers, industry analysts, and developers have complained about.

What many of those people don't understand is that the true power of the Playstation 3 doesn't lie in the memory, but in the eight-core architecture of the Cell processor. The Cell processor can handle a lot of physics objects because it's very math intensive, but struggles with memory intensive coding, which challenges developers to completely rework their game structure.

325w ago - At the heart of Sony Computer Entertainment's breakthrough PLAYSTATION 3 system is the Cell Broadband Engine (Cell BE) processor. The Cell BE is a multi-core processor employing a PowerPC processor element (PPE) and seven synergistic processor elements (SPE) to provide supercomputer capability in a home computer entertainment system. The Cell BE is capable of 218 GFlops performance.

PS3 as we all know is powered by 256mb of GDDR3 RAM and 256mb of XDR at ultrafast speed of 3.2ghz. The XDR RAM has a very low latency and is more efficient than contemporary PC RAMs.

So what exactly is XDR RAM and why is it superior to conventional PC RAM?

Playstation 3 XDR Memory Architecture video

50°
370w ago - The Rambus XDRâ„¢ memory architecture is a total memory system solution that achieves an order of magnitude higher performance than today's standard memories while utilizing the fewest ICs. Perfect for compute and consumer electronics applications, a single, 2-byte wide, 4.0 GHz XDR DRAM component provides 8.0 GB/s of peak memory bandwidth.

Video can be seen here. Key components enabling the breakthrough performance of the XDR memory architecture are:

XDR DRAM is a high-speed memory IC that turbo-charges standard CMOS DRAM cores with a high-speed interface capable of 4.0 GHz data rates providing up to 8 GB/s of bandwidth with a single device.

XIO controller IO cell provides the same high-speed signaling capability found on the DRAM, but adds additional enhancements like FlexPhaseâ„¢ technology that eliminates the need for trace length matching.

XMC memory controller is a fully synthesizable logical memory controller that is optimized to take advantage of innovations like Dynamic Point-to-Point which provides for capacity expansion while delivering the signal integrity benefits of point-to-point signaling.

XCG clock generator provides the system clocks with four programmable outputs and is guaranteed to...
