Abstract
A method of programming a NAND-type flash memory device having bitlines and wordlines, and memory strings composed of memory cells serially connected between string select transistors coupled to each of the bitlines and ground select transistors coupled to a source line. The method comprises of applying a first voltage to one or more unselected wordlines, then applying a predetermined bitline voltage to an unselected bitline, and then applying a second voltage to the unselected wordlines, and concurrently applying a third voltage to a selected one out of the wordlines. Thus, a program disturbance phenomenon can be prevented.
