Coding Last Level STT-RAM Cache For High Endurance And Low Power

STT-RAM technology has recently emerged as one of the most promising memory technologies. However, its major problems, limited write endurance and high write energy, are still preventing it from being used as a drop-in replacement of SRAM cache. In this paper, we propose a novel coding scheme for STT-RAM last level cache based on the concept of value locality. We reduce switching probability in…
