Abstract
A semiconductor memory over-driving scheme for a semiconductor memory device makes it possible to secure a high-speed sensing operation of a memory sense amplifier, regardless of a change of a power supply voltage. Over-driving efficiency is improved by controlling the discharging time and the drivability using different sized the drivers when the power supply voltage fluctuates while the bit line over-driving operation is performed.
