Abstract
According to one embodiment, a memory system includes a nonvolatile memory and a controller. The controller controls the nonvolatile memory, writes data to a random access memory in a host, and reads data from the random access memory. The random access memory includes regions in first units to which the controller is accessible. The controller uses encryption keys associated with the regions, respectively, for encrypting data to be written into each of the regions and decrypting data read from each of the regions.
