Abstract
A semiconductor memory device comprises a cell array including bit lines arranged at a uniform pitch; and a plurality of bit line selection transistors connected to respective bit line ends for selectively connecting the bit line to a sense amp. The bit line selection transistors are translationally arrayed in a direction perpendicular to the bit line at an average array pitch greater than eight times the pitch of the bit lines.
