  • Sense amplifier, memory and method for controlling sense amplifier
    Patent number: 11929111
    Abstract: A sense amplifier, a memory and a method for controlling the sense amplifier are provided. The sense amplifier includes: an amplification module, arranged to read data in a memory cell; and a control module, electrically connected to the amplification module. In a first offset compensation stage of the sense amplifier, the control module is arranged to configure the amplification module to include a first inverter and a second inverter, and each of the first inverter and the second inverter is an inverter an input terminal and an output terminal connected to each other; and in a second offset compensation stage of the sense amplifier, the control module is arranged to configure the amplification module to include a current mirror structure.
