Abstract
Provided herein is a memory device and a method of operating the memory device. The memory device includes memory cells coupled to a word line, a peripheral circuit configured to perform a program operation of increasing threshold voltages of the memory cells to threshold voltages corresponding to a target program state among a plurality of program states, and a program operation controller configured to determine whether to perform an erase state verify operation of identifying threshold voltages of erase cells having an erase state as the target program state among the memory cells.
