Abstract:
Disclosed is a semiconductor memory device and a method of operating the same. The semiconductor memory device includes a memory cell array including a plurality of memory blocks, a peripheral circuit configured to perform an erase characteristic check operation and an erase operation on the plurality of memory blocks. The semiconductor memory device also includes a control logic configured to control the peripheral circuit to perform the erase characteristic check operation and the erase operation, determine whether each of the plurality of memory blocks has a normal erase characteristic or an overerase characteristic according to a result of the erase characteristic check operation for each of the plurality of memory blocks, and set an erase voltage of the erase operation.

Claim (Index 14):
A semiconductor memory device, comprising:\n a memory cell array including a plurality of memory blocks; a peripheral circuit configured to sequentially perform an erase voltage application operation, a first erase verification operation, and a second erase verification operation on the plurality of memory blocks; and a control logic configured to control the peripheral circuit to perform the erase voltage application operation, the first erase verification operation, and the second erase verification operation, and generate data corresponding to an erase characteristic of each of the plurality of memory blocks according to results of the first erase verification operation and the second erase verification operation.
