Patent number: 10795772Abstract: A memory system includes a volatile memory, a nonvolatile memory, and a controller. The controller is configured to execute a non-volatilization process to store data in the volatile memory into the nonvolatile memory in response to an initiate request received by the controller if no cancellation request is received by the controller during a cancelable period that begins upon receipt of the initiate request by the controller, and to transmit a completion notification when the non-volatilization process has completed.Type: GrantFiled: May 29, 2018Date of Patent: October 6, 2020Assignee: TOSHIBA MEMORY CORPORATIONInventors: Hiroyasu Nakatsuka, Mikiya Kurosu, Yasuo Kudo
