Abstract

Disclosed is a sense amplifier which includes a pre-amplifier that is connected between an input node receiving an input signal and a first node, a second switch connected between the first node and a first output node outputting an output signal, an amplifier connected between the first output node and a second output node outputting an inverted output signal, and a second switch connected between the input node and the second output node. The pre-amplifier includes an inverter connected between the input node and the first node, and a third switch connected between the input node and the first node.
