Abstract
In an exemplary aspect, the present invention provides a semiconductor memory device including sense amplifiers that drive bit lines to which memory cells are connected, and driver transistors that supply a power supply to the sense amplifiers, wherein the sense amplifiers are arranged in rows and constitutes a first sense-amplifier row in which transistors of a first conductive type are arranged and a second sense-amplifier row in which transistors of a second conductive type are arranged, and the driver transistors constitutes at least one transistor row including a first driver transistor of the first conductive type corresponding to the first sense-amplifier row and a second driver transistor of the second conductive type corresponding to the second sense-amplifier row between the first sense-amplifier row and the second sense-amplifier row.
