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, configured to read data in a storage unit on a bit line or a storage unit on a reference bit line; and a first switch module, configured to control the amplification module to be disconnected from the reference bit line when the sense amplifier reads a first state for the bit line and the sense amplifier is in an amplification stage, and control the amplification module to be connected to the reference bit line when the sense amplifier reads a second state for the bit line and the sense amplifier is in the amplification stage. The present disclosure can reduce the power consumption of the sense amplifier.
