ABSTRACT:
A sense amplifier overdriving circuit includes a first voltage driver which supplies an internal voltage from an internal voltage terminal to a sense amplifier in response to a first enabling signal, a logic unit which logically operates a block select signal for selection of a cell block and a second enabling signal enabled for a predetermined time after enabling of the first enabling signal, and outputs the resultant signal, and a second voltage driver which supplies an external voltage to the internal voltage terminal in response to the signal output from the logic unit. The sensing amplifier overdriving circuit may be used in a semiconductor device.
