Assignee: ANHUI UNIVERSITY
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A sense amplifier, comprising:
an amplification module, configured to read data in a storage unit on a first bit line or a second bit line; and
a control module, electrically connected to the amplification module;
wherein when the data in the storage unit on the first bit line is read, in a first amplification phase of the sense amplifier, the control module is configured to configure the amplification module to comprise a first current mirror structure and connect a mirror terminal of the first current mirror structure to the second bit line; and
when the data in the storage unit on the second bit line is read, in the first amplification phase of the sense amplifier, the control module is configured to configure the amplification module to comprise a second current mirror structure and connect 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.
