Abstract
Provided herein is a semiconductor memory device and an operating method thereof. The semiconductor memory device may include a memory cell array, peripheral circuits, and a control logic. The memory cell array may include memory cells grouped into a plurality of pages. The peripheral circuits may perform a program operation for the plurality of pages. The control logic may control the peripheral circuits to perform the program operation by applying program voltages gradually increasing by a first step voltage to a selected page of the plurality of pages and by applying pass voltages gradually increasing by second step voltages to unselected pages of the plurality of pages. The second step voltages may vary depending on a position of the memory cells of the unselected pages in the memory cell array.
