Patent attributes
Sense amplifier, memory and control method are provided. The sense amplifier includes: amplify module configured to amplify voltage difference between bit line and reference bit line when the sense amplifier is in amplifying stage; write module connected to the bit line and the reference bit line, and configured to pull the voltage difference between the bit line and the reference bit line according to data to be written when the sense amplifier is in write stage; controllable power module connected to the amplify module, configured to provide first voltage to the amplify module when the sense amplifier is in non-write stage, and to provide second voltage to the amplify module when the sense amplifier in write stage. Herein, the second voltage is less than the first voltage, and the second voltage is in positive correlation with the drive capability of the write module.
