1. A sense amplifier, comprising:
an amplification circuit configured to amplify a voltage transmitted by a bit line or a reference bit line, when the sense amplifier is at an amplification stage;
a first switch circuit configured to control the amplification circuit to be disconnected from the reference bit line, when the sense amplifier performs a read operation on the bit line and the sense amplifier is at the amplification stage; and
a discharge control circuit configured to discharge the sense amplifier after the sense amplifier performs a read ‘1’ operation on the bit line.
