A method of programming a flash memory device controls a channel boosting level to ensure device properties. The flash memory device is programmed in an Incremental Step Pulse Program (ISPP) manner by applying a program voltage to a selected memory cell and a pass voltage to unselected memory cells. The programming is performed by varying the pass voltage so that a gap of a predetermined range is maintained between a channel voltage and a word line voltage of the unselected memory cell.
