Abstract
A semiconductor memory device comprises a plurality of cell arrays, each cell array containing a plurality of word lines, a plurality of bit lines crossing the word lines, and memory cells connected at intersections of the word lines and bit lines, the cell arrays arranged along the bit line; a plurality of bit line gates provided between the cell arrays and each operative to establish a connection between the bit lines in adjacent cell arrays; and a controlling circuit operative to form a data transfer path via the connection between the bit lines formed through the bit line gate when the controlling circuit accesses to the memory cell.
