MEMORY MODULE, ELECTRONIC DEVICE AND METHOD

摘要

According to one embodiment, a memory module includes a volatile memory, a nonvolatile memory, and a controller. The volatile memory is data readable and writable. The nonvolatile memory is data readable and writable and stores therein correspondence information containing an attribute indicating any of volatile, nonvolatile, and both of volatile and nonvolatile associated with an address in an address space assigned to the volatile memory and the nonvolatile memory. The controller reads data from and writes data to the volatile memory or the nonvolatile memory, referring to the correspondence information.
