ABSTRACT:
A bit line sense amplifier circuit for restoring and sensing data on a bit line in a semiconductor device. The bit line sense amplifier circuit comprises a first restore signal circuit including a PMOS transistor. The PMOS transistor is operated in response to a first clock signal. The bit line sense amplifier circuit further comprises a first sensing signal circuit including an NMOS transistor. The NMOS transistor is operated in response to a second clock signal. The bit line sense amplifier circuit further comprises a second restore signal circuit being operated in response to a first control signal and a third clock signal, and a second sensing signal circuit being operated in response to a second control signal and a fourth clock signal. The first and second restore signal circuits are connected in parallel to each other. Similarly, the first and second sensing signal circuits are connected in parallel to each other.
