Abstract
Provided herein is a memory device and a method of performing a verify operation of the memory device. The memory device includes a memory cell array including memory cells, a source line discharge transistor configured to couple a source line of the memory cell array to a ground, a voltage generator configured to generate a gate voltage that is applied to a gate of the source line discharge transistor, and a control logic configured to determine the gate voltage depending on changes in threshold voltages of the memory cells in response to a verify operation on the memory cells performed in each of a plurality of program loops and to control the voltage generator to generate the determined gate voltage.
