CONSTITUTION: Source selection lines(SSL'), source lines, word lines(WL'), and drain selection lines(DSL') are separated from each other. A plurality of bit lines(BL') are orthogonal to the word line. A metal line is arranged in the same direction as the source line. The metal line is arranged under the bit line.</p> |
