MEMORY SYSTEM WITH ENHANCED SECURITY ACCESS TO PARITAL STORAGE AREAS

Abstract

According to one embodiment, a memory system includes a nonvolatile memory and a controller. The controller enables a first access authority to a first storage area which is at least a partial storage area of the nonvolatile memory and sets a first time limit at which the first access authority becomes disabled. The first access authority is assigned to first user identification information. The controller disables the first access authority in a case where current time exceeds the first time limit.
