Abstract:
1. An apparatus for generating a driving voltage for a sense amplifier in a memory device, the apparatus comprising: voltage output means for outputting a predetermined value of voltage for driving the sense amplifier to a node being used as a driving voltage node of the sense amplifier; a first core voltage step-up means connected between a power supply and the node; and a second core voltage step-up means connected between the power supply and the node, wherein the first core voltage step-up means is turned on to elevate the voltage level of the node up to the level of the power supply at a first rate, and wherein, any time after the first core voltage step-up means is initially turned on, the second core voltage step-up means is turned on to elevate the voltage level of the node up to the level of the power supply at a second rate.
