Claim:
1. A sense amplifier driving device, comprising: a power driving unit configured to supply a first pull-up voltage and a pull-down voltage to a pull-up power line and a pull-down power line during a post-overdriving period; and a driving signal generation unit configured to generate a pull-up driving signal and a pull-down driving signal activated during the post-overdriving period in order to control a driving of the power driving unit, wherein the driving signal generation unit controls a point of time at which the pull-down driving signal shifts in response to a post-overdriving enable signal, wherein the driving signal generation unit comprises: a control signal generation unit configured to perform pull-up or pull-down driving on a pull-down pre-signal in response to an active signal and a precharge signal; a delay unit configured to delay the pull-down pre-signal; a selection unit configured to select one of the pull-down pre-signal and an output of the delay unit in response to the post-overdriving enable signal; and a driving unit configured to output the pull-down driving signal by driving the output of the selection unit.
