Abstract:
According to one embodiment, a memory system includes a memory and controller. The controller repeatedly performs an erase voltage application process for data stored in a target area in the memory. The controller performs an erase verification process for determining whether the erase is successful using erase verification voltage. The controller determines whether an erase time is longer than a first threshold value. The controller sets the target area to a use prohibition state when the erase time is longer than the first threshold value.

Claim (Index 1):
A memory system comprising:\n a nonvolatile memory; and a controller controlling to the nonvolatile memory, wherein the controller is configured to repeatedly perform an erase voltage application process for data stored in an erase target area in the nonvolatile memory, perform an erase verification process for determining whether the erase of the data is successful using erase verification voltage, the erase verification process corresponding to each of the repeatedly performed erase voltage application processes, change, when the erase of the data is not successful in the erase verification process, the erase verification voltage to new erase verification voltage to be used in a next erase verification process, determine, when the erase of the data is successful, whether an erase time is longer than a first threshold value, the erase time being a time that the controller takes to determine that the erase of the data in the erase target area is successful, and set the erase target area to a use prohibition state when the erase time is longer than the first threshold value.
