Abstract
Provided is a semiconductor memory device and a method of operating the same. The semiconductor memory device may include a memory unit including a plurality of memory blocks; a voltage supply circuit configured to generate a plurality of operating voltages and output the generated operating voltages to at least two global line groups during a program operation on the memory unit; a pass circuit configured to couple word lines of the memory blocks to the at least two global line groups; and a control logic configured to control the voltage supply circuit and the pass circuit such that during a program verify operation of the program operation, a program verify voltage is applied to a selected memory block of the memory blocks, and a set voltage is applied to a share memory block sharing with the selected memory block among unselected memory blocks.
