Abstract
A NAND flash memory device having a facing bar and a method of fabricating the same are provided. The method includes forming one transistor or a plurality of stack transistors as cell transistors on two side surfaces of a facing bar to have transmission channels thereat. In this case, the height of the facing bar may be easily increased. Thus, not only a layout area of unit transistors including the cell transistors but also a layout area of cell strings may be minimized, and lengths of the transmission channels of the cell transistors may be sufficiently extended. As a result, according to the NAND flash memory device and the method of fabricating the same, the overall operating characteristics are improved.
