MECHANISM ENABLING THE USE OF SLOW MEMORY TO ACHIEVE BYTE ADDRESSABILITY AND NEAR-DRAM PERFORMANCE WITH PAGE REMAPPING SCHEME

摘要

Memory systems may include a memory storage including a dynamic random access memory (DRAM) portion, a non-volatile memory (NVM) portion, and a virtual memory (VM), a software page remapping kernel driver (SPRKD) suitable for intercepting a memory management command, the memory management command including an access to a virtual address location of the VM, and remapping the virtual address location from a physical address of the NVM portion mapped to the virtual address location to a physical address of the DRAM portion, and a controller suitable for executing the memory management command by accessing the physical address of the DRAM portion to which the virtual address location is remapped.
