Original Abstract Submitted

A semiconductor memory device includes a memory block, a peripheral circuit, and a control logic. The memory block includes memory cells. The peripheral circuit performs a program operation including program loops on selected memory cells. The control logic controls the peripheral circuit to apply a program inhibit voltage to bit lines connected to memory cells of a first group of target states, apply the program inhibit voltage to bit lines connected to memory cells on which programming is determined to be completed in a previous program loop, among memory cells of a second group of target states, and apply a program allowable voltage to bit lines connected to memory cells on which programming is determined to not be completed in the previous program loop, among the memory cells of the second group of target states. The first and second groups are determined by a number of current program loops.
