  • Sense amplifier, storage device and read-write method
    Patent number: 11862283
    Abstract: A sense amplifier includes a first switch unit, a second switch unit, and an amplifier-latch module. A first port of the amplifier-latch module is electrically connected, via the first switch unit, to a bit line connected with a storage unit, and a second port of the amplifier-latch module is electrically connected to a reference voltage signal via the second switch unit. The amplifier-latch module is configured to amplify a signal in a sensing amplification phase. The first switch unit is configured to transmit a voltage on the bit line to the first port before the sensing amplification phase. The second switch unit is configured to transmit the reference voltage signal to the second port before the sensing amplification phase, and disconnect an electrical connection between the reference voltage signal and the second port in the sensing amplification phase.
