IBM's eDRAM May Reduce Future CPU Bottlenecks
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's "eDRAM" or embedded DRAM will help boost performance in future multi-core processors, especially in gaming and multimedia applications, with significantly reduced latencies.
IBM said it has been able to speed up the DRAM to the point where it's nearly as fast as SRAM, and that the result is a type of memory known as 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. DRAM will also continue to be used off the chip.
