Abstract
The demands of larger memory capacity in high-performance computing systems have motivated the researchers to explore alternatives of dynamic random access memory (DRAM). Since phase change memory (PCM) provides high-density, good scalability and non-volatile data storage, it has received significant amount of attention in recent years. A crucial bottleneck in wide-spread adoption of PCM, however, is that its write latency and energy are very high. Recently, several architecture and system-level techniques have ...
