  • Publication number: 20170161185
    Abstract: A memory mapping management method for a system using nonvolatile memory (NVM) as main memory, including receiving a request to cancel a memory mapping, determining whether the memory mapping is a mapping of a file based on meta data relating to the memory mapping, separately storing the meta data when the memory mapping is the mapping of the file, and cancelling the memory mapping when the memory mapping is not the mapping of the file may be provided. Further, the memory mapping management method may include receiving a memory mapping request, searching for a memory mapping for a file in a memory mapping storage space when a requested memory mapping is a mapping of the file, and reusing a searched memory mapping found during the search when a region of the searched memory mapping includes a region required by the requested memory mapping in a virtual address space.
