Abstract:
This semiconductor memory device comprises a plurality of sub-arrays with a plurality of memory cells arranged in matrix form. Each local bit line is connected to a plurality of memory cells that are arranged in column direction in the sub-arrays. In addition, a global bit line is connected to the plural local bit lines. A column decoder is connected to the global bit line. The global bit line extends from the column decoder toward the plurality of sub-arrays, and it is cut before the furthest sub-array formed in the furthest region from that column decoder.
