Abstract
This paper presents novel processor architecture for HP-processor with nonvolatile/volatile hybrid cache memory. By simulations of high-performance (HP)-processor using MTJs, it has been clarified that total power of the HP-processor using perpendicular-(p-)STT-MRAM can be reduced by over 90 % with little degradation of processor performance. The presented architecture with nonvolatile memory hierarchy will realize the “normally-off computers”.
