A sense amplifier control circuit which can be used in a semiconductor device includes an enable signal generator for decoding a plurality of internal commands, to output a first enable signal and a second enable signal which are enabled in an active mode of a semiconductor device, a first driving control signal generator for generating a first driving control signal adapted to control a driving period of a pull-down source line of a sense amplifier included in the semiconductor device, a second driving control signal generator for comparing a voltage level of a pull-up source line of the sense amplifier with a predetermined internal voltage, and generating a second driving control signal which is enabled when the voltage level of the pull-up source line is higher than the internal voltage, to control the driving period of the pull-up source line, and a third driving control signal generator for generating a third driving control signal which is disabled in response to enabling of the second driving control signal, to control an over-driving period of the pull-up source line.
