Summary:
Traditional computers use DRAM for their main memory. NVRAM (Non-volatile random-access memory) is a newly emerging memory. It can keep its data after power-off, but its performance is less than that of DRAM. Also, its performance is higher than usual persistent storage, such as SSD and HDD, and its cost per bit ratio is also higher. Some of the most promising ways to utilize NVRAM are to construct a mixture of DRAM and NVRAM memory or a mixture of HDD/SSD and NVRAM persistent storage with techniques for storing frequently used data in faster storage. In this paper, we discuss the performance of a mixture of DRAM and NVRAM memory with dynamic data migration with NVRAM emulation including software delay. We then show that its performance is higher than that without dynamic migration.
