ABSTRACT:
A semiconductor memory device includes a sub array including a plurality of memory cells each holding data arranged therein; a memory cell array including a plurality of the sub arrays arranged therein; paired bit lines including a first bit line and a second bit line connected to each of the sub arrays; and a write/read circuit arranged to correspond to each of the sub arrays, writing data to the sub array, and reading data from the sub array, wherein a pair of the sub array and the write/read circuit is repeatedly arranged along the paired bit lines, allowing the data to be transferred via the write/read circuit and the paired bit lines.
