WoM-SET: Low power proactive-SET-based PCM write using WoM code

Abstract

The emerging Phase Change Memory (PCM), while having many advantages, suffers from slow write operations. This is mainly due to its asymmetric write characteristic, i.e., for two types of write operations of PCM, SET is much slower than RESET. Recent study has shown that proactively setting dirty memory lines to all '1's can enable RESET-only writes when… (More)
