Abstract

A method of performing a programming operation to a three dimensional (3D) NAND memory device is disclosed. The method makes residual electrons trapped in storage regions of middle dummy memory cells of the unselected string of the 3D NAND memory device to be removed during the pre-charging phase, so as to reduce program disturb to the selected string which neighbors the unselected string.
