Abstract
A sense amplifier circuit for a semiconductor device which can reduce current consumption by reducing the operation time of a pull-up driver for supplying the power voltage to a sense amp when a power voltage is higher than a reference voltage, and which can improve operation properties by increasing the operation time of the pull-up driver when the power voltage is lower than the reference voltage. The sense amplifier circuit includes: a first and a second pull-up drivers; a first and a second pull-down drivers; a voltage detecting unit; and selecting driver unit for respectively controlling operations of the first and the second pull-up drivers and the first and the second pull-down drivers according to the output signal of the voltage detecting unit.
