1. A sense amplifier, comprising:
a voltage comparator with offset compensation, coupled to a bit line and a reference bit line via a first I/O node and a second I/O node of the sense amplifier respectively, and configured to compare a first input voltage and a second input voltage to output a sensing signal;
a first clamping circuit, coupled between the first I/O node of the sense amplifier and the bit line; and
a second clamping circuit, coupled between the second I/O node of the sense amplifier and the reference bit line,
wherein at least one of the first clamping circuit and the second clamping circuit perform a trimming correction function for matching a first threshold voltage of the first clamping circuit with a second threshold voltage of the second clamping circuit.
