Abstract
A bit line pre-charge voltage generating circuit in a semiconductor memory device may reduce current consumption. The bit line pre-charge voltage generating circuit includes a reference voltage generating portion that generates a pull-down reference voltage and a pull-up reference voltage; a comparing portion that generates a pull-up comparison signal by comparing the level of the bit line pre-charge voltage with that of the pull-up reference voltage, and generates a pull-down comparison signal by comparing the level of the bit line pre-charge voltage with that of the pull-down reference voltage; a driving portion that includes a pull-up driving element and a pull-down driving element; and an activation overlap reduction portion that generates the pull-up control signal and the pull-down control signal The activation overlap reduction portion can minimize the overlap between the turn-on sections of the pull-up driving element and the pull-down driving element of the driving portion.
