Abstract:
1. A sense-amplifier driving device, comprising: a sense-amplifier driver 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 period, provide a second pull-up voltage and the first pull-down voltage to the pull-up power line and the pull-down power line, respectively, during an active time period, and provide a third pull-up voltage and a second pull-down voltage to the pull-up power line and the pull-down power line, respectively, during a second over-driving time period; and a drive-signal generator configured to generate a plurality of drive signals, which is selectively activated during the first over-driving time period, the active time period, and the second over-driving time period, to control the sense-amplifier driver.
