Abstract
In a programming method of a non-volatile memory device, a program operation is performed by applying a program voltage to a selected word line and a first pass voltage to unselected word lines. The first pass voltage shifts to a second pass voltage having a level lower than that of the first pass voltage. A verify operation is performed by applying a verify voltage to the selected word line. The verify voltage has a level lower than that of the second pass voltage.
