US Patent 12094562 Sense amplifier, memory, and control method

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; and a controlled power supply module, connected to the amplification module, and configured to: determine a drive parameter according to a first rated pull rate range and a second rated pull rate range, and supply power to the amplification module according to the drive parameter, to control the amplification module to pull a voltage of the bit line or a voltage of the reference bit line to a first preset value at a first rated pull rate at the amplification stage and pull the voltage of the reference bit line or the voltage of the bit line to a second preset value at a second rated pull rate at the amplification stage.
