IBM Speeds Up DRAM

IBM unveiled its eDRAM, an evolution of DRAM aimed to boost performance of chips. It works by swapping out most of the static random access memory (SRAM), used to store information directly on computer chips and integrating onto the chip another kind of memory, known as dynamic random access memory (DRAM). SRAM is a fast memory but it is part of the processor chip, making it difficult to extend its capacity at will. DRAM is the most common memory type found in our computer on separated modules, but its access times are slower than SRAM.
What IBM has achieved, is the get the best of both RAM types to create a DRAM almost as fast as the SRAM while being physically separated from the chip. They named it embedded DRAM, or eDRAM, while being off the chip, it will boost the performance of multiple core calculating engines and will be particularly interesting for graphics rendering and movement calculation in gaming and other multimedia applications.
IBM expects to integrate this technology to its server chips beginning of 2008, and from then extend it to its entire line of products. One can also imagine that IBM will license out this technology to GPU designers.
