Abstract

The present disclosure provides a sense amplifier, a memory, and a method for controlling a sense amplifier, relating to the technical field of semiconductor memories. The sense amplifier comprises: an amplification module; and a control module, electrically connected to the amplification module; wherein, in an offset compensation stage of the sense amplifier, the control module is used to configure the amplification module to comprise a diode structure, a current mirror structure, and an inverter with an input and an output connected together; and in a first amplification stage of the sense amplifier, the control module is used to configure the amplification module as an inverter. The present disclosure can realize the offset compensation of the sense amplifier, thereby improving the performance of semiconductor memories.
