Abstract
A sense amplifier driving device, and more particularly, a technology for improving the post overdriving operation characteristic of a semiconductor device. A sense amplifier driving device includes a driving signal generation block configured to compare a reference voltage set by a voltage trimming signal and a level of a power supply voltage, and generate a pull-up driving signal for controlling an operation of a sense amplifier; and a sense amplifier driving block configured to supply a driving voltage to a pull-up power line of the sense amplifier for an active operation period in correspondence to the pull-up driving signal, the driving signal generation block including a voltage divider configured to divide the power supply voltage, and output a divided voltage; and a voltage comparison section configured to compare the reference voltage and the divided voltage, and output a control signal for controlling an overdriving operation of the sense amplifier.
