IBM's eDRAM May Reduce Future CPU Bottleneck

"IBM has found a way to allow memory to deliver data closer to the rate at which processors request it by replacing embedded SRAM in computer chips with a new kind of DRAM developed specifically for use in microprocessors."

IBM claims that it has worked out a way of curing hardware of memory bottlenecks by replacing SRAM with DRAM. According to Associated Press reports, the design will triple the amount of memory stored on computer chips and double the performance of processors.

IBM said its solution entails swapping out most of the static random access memory, or SRAM, used to store information directly on computer chips and integrating onto the chip another kind of memory, known as dynamic random access memory, or DRAM.

SRAM is a type of memory that's fast and easy to manufacture but takes up a lot of valuable real estate on the chips. DRAM, the most common type of memory used in personal computers, has typically been stored on a separate chip and has previously been viewed as too slow to be integrated directly onto the microprocessor.

IBM said it has been able to speed up the DRAM to the point where it's nearly as fast as SRAM. This creates embedded DRAM, or eDRAM, that helps boost the performance of chips with multiple core calculating engines and is particularly suited for enabling the movement of graphics in gaming and other multimedia applications.

Apparently, according to IBM the technology will be included in its server chips starting in 2008 and will expand to other products.

Mr. Popo
IBM says it is developing new circuitry that could triple the data stored on a typical microprocessor, and thereby double the performance of computers. The computer maker's approach is based on exploiting the most widely used memory technology in a new way. IBM researchers will discuss their progress at a conference in San Francisco on Wednesday.
