  • Patent number: 10795772
    Abstract: 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.

  • Publication number: 20140075100
    Abstract: A memory system includes a non-volatile memory having a physical memory region and a controller for conducting data transmission between the non-volatile memory and a host. The controller includes a section management module and a wear leveling module. The section management module divides the physical memory region into multiple sections including a first section and one or more of second sections. The wear leveling module performs independent wear leveling for each of the second sections without performing wear leveling for the first section. The section management module performs expansion of the first section according to a physical memory region expansion request from the host.
