Abstract
The disclosure provides a Sense Amplifier (SA), a memory and a method for controlling the SA, and relates to the technical field of semiconductor memories. The SA includes: an amplifier module; an offset voltage storage unit electrically connected to the amplifier module and configured to store an offset voltage of the amplifier module in an offset elimination stage of the SA; and a load compensation unit electrically connected to the amplifier module and configured to compensate a difference between loads of the amplifier module in an amplification stage of the SA. The disclosure may improve an accuracy of reading data of the SA.
