Abstract:
Provided herein are a semiconductor memory device and a method of operating the semiconductor memory device. The semiconductor memory device having improved reliability includes a memory cell array including memory cells coupled to a plurality of word lines, a peripheral circuit configured to perform a program operation on a word line selected from among the plurality of word lines, and control logic configured to control the peripheral circuit so that, when the selected word line is a reference word line during the program operation, a partial erase operation is performed on memory cells included in a memory cell group corresponding to the reference word line.

Claim (Index 1):
A semiconductor memory device, comprising:\n a memory cell array including a plurality of memory blocks; a peripheral circuit configured to erase a memory block selected from among the plurality of memory blocks; and control logic configured to control the peripheral circuit so that a threshold voltage of memory cells included in a first word line group, among the plurality of memory cells included in the selected memory block, is erased in a first erase state, and memory cells included in a second word line group corresponding to word lines other than the first word line group are erased in a second erase state, wherein a threshold voltage in the first erase state has a level lower than that of a threshold voltage in the second erase state.
