Abstract:
A semiconductor memory device includes a memory cell array configured to store data; peripheral circuits configured to perform program verifying operation, read operation, and erase verifying operation on the memory cell array; and a control circuit configured to control the peripheral circuits, wherein the control circuit is configured to control the peripheral circuits to set a bit line voltage in the program verifying operation to have a higher level than a bit line voltage in the read operation, and a bit line voltage in the erase verifying operation to have a lower level than the bit line voltage in the read operation.
