To prevent a layout area from being expanded while preventing characteristics of pair transistors from being deteriorated in a semiconductor memory device continuously arraying a plurality of pair transistors each including a predetermined function.

A semiconductor memory device repeatedly arraying a plurality of pair transistors each including a predetermined function includes a plurality of pair transistors comprised of transistors adjacent in a row direction, a plurality of pair transistors comprised of transistors of which a mutual arrangement relationship is oblique, and a group of pair transistors arraying the plurality of pair transistors combining them.
