Understanding the limiting factors of page migration in hybrid main memory
Santiago Bock, Bruce R. Childers, Rami Melhem, Daniel Mossé · 2015
Combining DRAM and non-volatile memory (NVM) has been proposed to increase capacity and reliability, and to decrease energy consumption. Software-managed hybrid memory is a promising way to incorporate NVM in main memory due to its architectural simplicity. However, there are significant performance issues caused by interference in the memory system due to data migration between DRAM and NVM and a lack of effective migration policies.
