Phase change memory (PCM) is a promising technology that can offer higher capacity than DRAM. Unfortunately, PCM's access latency and energy are higher than DRAM's and its endurance is lower. Many DRAM-PCM hybrid memory systems use DRAM as a cache to PCM, to achieve the low access latency and energy, and high endurance of DRAM, while taking advantage of PCM's large capacity. A key question is what data to cache in DRAM to best exploit the advantages of each technology while avoiding its disadvantages as much as possible. We propose a new caching policy that improveshybrid memory performance and energy efficiency. Our observation is that both DRAM and PCM banks employ row buffers that act as a cache for the most recently accessed memory row....
