基于新型非易失存储器的混合内存架构的内存管理机制

With the rapid development of internet and cloud computing technology, the existing dynamic random access memory (DRAM) have been unable to meet the requirements of performance and energy consumption of some real time systems.The emergence of non-volatile memory (NVM) have shown great potential for the development of the computer storage architecture.This paper proposes a kind of efficient memory page management mechanism based on the hybrid NVM and DRAM memory architecture.The main idea of this mechanism is to save the data pages with different access characteristics in the appropriate memory space according to the characteristics of different memory media, to reduce the number of system migration operations and improve the system performance.At the same time, the mechanism uses an efficient wear-leveling algorithm to improve NVM's lifetime.Finally, the experimental results show that the proposed method is effective.
