Abstract
A flash memory device including a controller to determine higher, M, and lower, N, word-line address bits based on an input word-line address, to determine a selected area of a memory array based on the higher and lower word-line address bits, and an unselected area of the memory array based on the selected area; and a high voltage generator to provide a first pass voltage to a word line of the selected area, and to provide a second pass voltage to a word line of the unselected area. The pass voltages are discriminately applied to the programmed and non-programmed memory cells, enlarging the pass voltage window. The memory array is divided into pluralities of zones to which local voltages are each applied in different levels.
