Abstract
According to one embodiment, a memory system includes a controller. The controller manages a plurality of flags corresponding to a plurality of physical addresses. In response to receiving a read command from a host, the controller acquires from a first management table a physical address mapped to a logical address specified by the read command, and reads data from a nonvolatile memory based on the acquired physical address. The controller determines whether or not to transmit the read data to the host based on whether a current status of the flag corresponding to the acquired physical address is set to a first value indicating valid data or to a second value indicating invalid data.
