Abstract
A selected word line that is coupled to cells for programming is biased with an initial programming voltage. The unselected word lines that are adjacent to the selected word line are biased at an initial Vpass. As the quantity of program/erase cycles on the memory device increases, the programming voltage required to successfully program the cells decreases incrementally. Vpass tracks the decrease of the programming voltage.
