Patent attributes
The present application provides a sense amplifier, a memory, and a control method. The sense amplifier includes: an amplification module, configured to amplify a voltage difference between a bit line and a reference bit line when the sense amplifier is at an amplification stage; and a controlled power module, connected to the amplification module, and configured to: determine a drive parameter according to a rated compensation voltage range between the bit line and the reference bit line, and supply power to the amplification module according to the drive parameter, so as to control the amplification module to pull a compensation voltage between the bit line and the reference bit line to be a rated compensation voltage at an offset cancellation stage, where the rated compensation voltage is within the rated compensation voltage range.
