Hybrid Main Memory for High Bandwidth Multi-Core System
IEEE Transactions on Multi-Scale Computing Systems（2015）
摘要
In the hybrid main memory sub-system which consists of DRAM and phase change RAM (PRAM), DRAM is often used as a cache. Such a configuration of DRAM cache and PRAM main memory has two problems. First, it requires high bandwidth of data movement between DRAM and PRAM due to the large granularity (i.e., DRAM row) of caching. Second, the memory bandwidth of PRAM is not fully utilized since it can be ...
