Abstract
A semiconductor device includes strings each having a plurality of memory cells. The strings are coupled between a common source line and a bit line. A method of operating the semiconductor device includes applying a pre-program voltage to a selected word line coupled to a selected memory cell and to an unselected word line coupled to an unselected memory cell adjacent to the selected memory cell among the plurality of memory cells. The method further includes applying a first program voltage to the selected word line.
