Claim 17:
18. A method for controlling a sense amplifier, the sense amplifier comprising an amplification circuit and a control circuit electrically connected to the amplification circuit, the amplification circuit comprising a plurality of transistors and the control circuit comprising a plurality of switches, and the method for controlling the sense amplifier comprising:
in a first offset compensation stage of the sense amplifier, controlling, by the control circuit, through controlling on-off states of the plurality of switches by receiving at least one control signal, the plurality of transistors of the amplification circuit to form a first inverter and a second inverter, each of the first inverter and the second inverter being an inverter with an input terminal and an output terminal connected to each other;
in a second offset compensation stage of the sense amplifier, controlling, by the control circuit, through controlling the on-off states of the plurality of switches by receiving the at least one control signal, a first part of the plurality of transistors of the amplification circuit to form a current mirror structure;
in a case of reading data in a memory cell on a first bitline, in a first amplification stage of the sense amplifier, controlling, by the control circuit, through controlling the on-off states of the plurality of switches by receiving the at least one control signal, a second part of the plurality of transistors of the amplification circuit to form a third inverter; and
in a case of reading data in a memory cell on a second bitline, in the first amplification stage of the sense amplifier, controlling, by the control circuit, through controlling the on-off states of the plurality of switches by receiving the at least one control signal, a third part of the plurality of transistors of the amplification circuit to form a fourth inverter.
