Original Abstract Submitted
According to one embodiment, a controller, in response to receiving, from a host, a first command requesting secure erase of secure erase target data associated with a first logical area identifier, stores a copy of first mapping information that corresponds to the first logical area identifier, among mapping information that is included in a first table. The controller executes at least a data erase operation for one or more first blocks storing the secure erase target data. In a first mode, the controller, in response to receiving, from the host, a read command that specifies the first logical area identifier, reads data from a storage location corresponding to a first physical address that is mapped to the first logical area identifier in the copy of the first mapping information.
