Original Abstract Submitted
A semiconductor device includes a memory cell array and a peripheral circuit. The memory cell array is coupled to a plurality of word lines and a plurality of bit lines. The peripheral circuit performs a deep-erase verification operation to determine whether a target memory cell has a threshold voltage that is lower than a first negative reference voltage by applying a second negative reference voltage that is lower than the first negative reference voltage to the target memory cell.
