Abstract:
According to one embodiment, a semiconductor memory device includes a memory cell array including a plurality of memory cells, a first register configured to store data of the memory cells, and a sequence control circuit configured to control the memory cell array and the first register. In at least a data read operation of the memory cells, the sequence control circuit reads out, from the memory cell array, data including flag information representing whether the number of failed bits is in an allowable range.
