Claim 16:
17. A method for controlling a sense amplifier comprising an amplification module and a control module, the method for controlling the sense amplifier comprising:
when data in a storage unit on a first bit line is read, in a first amplification phase of the sense amplifier, configuring, by using the control module, the amplification module to comprise a first current mirror structure and connecting a mirror terminal of the first current mirror structure to a second bit line; and
when data in a storage unit on the second bit line is read, in the first amplification phase of the sense amplifier, configuring, by using the control module, the amplification module to comprise a second current mirror structure and connecting a mirror terminal of the second current mirror structure to the first bit line;
wherein an operation phase of the sense amplifier comprises the first amplification phase and a second amplification phase, and a non-read bit line voltage is pre-amplified in a first direction during the first amplification phase, the first direction being opposite to a direction in which a read bit line voltage is amplified.
