Claim Text:
1. A non-volatile memory device having a vertical structure, the non-volatile memory device comprising: a substrate; a semiconductor pole formed on the substrate to extend vertically with respect to the substrate; a NAND string formed on the substrate to extend vertically with respect to the substrate and along sidewalls of the semiconductor pole, the NAND string comprising a plurality of control gate electrodes arranged along with the sidewalls of the semiconductor pole and at least one set of at least two selection gate electrodes arranged along with the sidewalls of the semiconductor pole adjacent to the plurality of control gate electrodes, wherein the at least one set of at least two selection gate electrodes has a first selection gate electrode and a second selection gate electrode; at least one set of at least two selection lines, the one set of at least two selection lines having a first selection line and a second selection line; and at least two contact plugs, the at least two contact plugs having a first contact plug connected between the first selection line and the first selection gate electrode and a second contact plug connected between the second selection line and the second selection gate electrode.
