Abstract

A bit line sense-amplifier for a semiconductor memory device and a method for driving the same do not apply a bit line precharge voltage by a switch in an equalization operation, perform an equalization operation by interconnecting a plurality of sense-amplifier lines, then perform a precharge operation by applying a bit line precharge voltage through NMOS transistor of the switch, increase a sensing speed by reducing a loading of a sense-amplifier, reduce a transient current, and minimize a power-consumption by performing a precharge operation after a bit line equalization.
