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 an offset voltage storage unit electrically connected to the amplification module; wherein, in an offset cancellation stage of the sense amplifier, the sense amplifier is configured to comprise a current mirror structure to store an offset voltage of the amplification module in an offset voltage storage unit. The present disclosure can realize the offset cancellation of the sense amplifier.
