Abstract
A bit line sense amplifier with an enhanced sensing margin is provided. The bit line sense amplifier includes a sensing amplification circuit connected to a bit line and a complementary bit line and configured to sense a voltage change of the bit line and adjust voltages of a sensing bit line. Also provided is a complementary sensing bit line based on the sensed voltage change, wherein the sensing amplification circuit includes a first transistor connected between the complementary sensing bit line and a first high-voltage node and controlled by the voltage change of the bit line. A second transistor is connected between the sensing bit line and a second high-voltage node and controlled by a voltage change of the complementary bit line.
