Abstract

A memory device, and an operating method of the memory device, includes a plurality of memory cells connected between word lines and bit lines and a voltage generator for generating a program voltage or a pass voltage, which is applied to the word lines. The memory device also includes a page buffer group for applying program allow voltages or a program inhibit voltage to the bit lines and a control circuit for controlling the voltage generator and the page buffer group in response to a command. In a program operation of selected memory cells connected to a selected word line among the word lines, the control circuit controls the page buffer group such that the program allow voltages are increased stepwise according to a number of program loops performed on the selected memory cells.
