<p>The present invention relates to a sense amplifier driving device and a semiconductor device including the same and, more particularly, to a technology for improving the refresh characteristics of a semiconductor device. The sense amplifier driving device includes: a power supply driving unit configured to provide a first pull-up voltage and a first pull-down voltage to a pull-up power line and a pull-down power line, respectively, during a first over-driving time section, and to provide the first pull-up voltage to the pull-up power line during a second over-driving time section; an over-driving controller configured to provide a second pull-down voltage lower than the first pull-down voltage to the pull-down power line during the second over-driving time section; and a drive signal generator configured to generate a drive signal activated for the first and second over-driving time sections so as to control a drive of the power supply driving unit.</p> |
