Claim 14:
15. The semiconductor memory device according to claim 1, comprising
a first wiring electrically connected to the first semiconductor layer, wherein
the semiconductor memory device is configured to be able to perform a read operation, a write operation, an erase operation, and a first operation,
in the erase operation, a first voltage is applied to the first conductive layer, and an erase voltage larger than the first voltage is applied to the first wiring,
in the first operation, the first voltage is applied to the first conductive layer, and a second voltage larger than the first voltage and smaller than the erase voltage is applied to the first wiring, and
the first operation is executed after executing the write operation to a memory cell corresponding to the first conductive layer before executing the read operation to the memory cell.
