Abstract
A non-volatile memory device includes a memory cell array and a controller. The memory cell array includes memory cells for data storage and a plurality of flag cells. The flag cells indicate program states of the memory cells for each of a plurality of word lines. The controller determines the program states of the memory cells by employing the flag cells and controls a pass voltage provided to a corresponding word line according to the determined program states.
