Classification: CPC G | IPC G

Claim 15:
16. A method for controlling a sense amplifier, wherein the sense amplifier comprises an amplify circuit, a controllable power circuit and a write circuit, and the method comprises:
obtaining a working state of the amplify circuit, and the working state comprising a write stage and a non-write stage; and
generating a control signal for controlling the controllable power circuit according to the working stage, to able the controllable power circuit to provide a first voltage to the amplify circuit in a non-write stage and to provide a second voltage to the amplify circuit in a write stage, and the second voltage is in positive correlation with a drive capability of a write circuit;
wherein a process of writing data into memory cells comprises an access stage, a sensing stage, the write stage and a recover stage; and the non-write data stage comprises the access stage, the sensing stage and the recovery stage.
