    Abstract: In a sense amplifier, a switching transistor is configured to apply a ground voltage to a ground node in response to a sense enable signal. A first detection circuit is configured to output a first detection signal to the first detection node based on a mode signal and a voltage of a bit-line. A second detection circuit is configured to output a second detection signal to the second detection node based on a voltage of a complementary bit-line. A latch circuit is connected to a supply voltage, the first detection node and the second detection node, and configured to output a first amplified signal and a second amplified signal through a latch node and a complementary latch node, respectively, based on the first detection signal and the second detection signal.
