基于写页面热度的混合内存页面管理策略

Hybrid-memory page management strategy based on write page popularity

针对阻变存储器(RRAM)写延迟大的问题,提出一种基于写页面热度的混合内存页面管理策略,将写页面进行冷热区分,存于动态随机访问存储器(DRAM)上,减少RRAM上的写数量.在基准程序集PARSEC下对混合内存系统的性能进行测试与分析.结果表明,所提出的页面管理策略可以有效地提高系统性能.

In order to solve the problem of high write latency of the resistive variable memory(RRAM),a hybrid-memory page management strategy based on write page popularity is proposed.It distinguishes the write pages by hot and cold,saves the hot-written pages on dynamic random access memory(DRAM),and reduces the number of writes on the RRAM.The performance of the hybrid memory system is tested and analyzed under the benchmark assembly PARSEC.The page management strategy proposed in this paper can effectively improve the system performance.
