    • A sense amplifier and method thereof are provided. The sense amplifier includes first and second transistors coupled to first and second bit lines, respectively. The first and second transistors are configured to connect the first and second bit lines to a differential amplifier during a first state (e.g., when a differential voltage is present on the first and second bit lines and prior to a sense signal transition) and to isolate the first and second bit lines from the differential amplifier during a second state (e.g., after the sense signal transition). The sense amplifier further includes a third transistor configured to deactivate the differential amplifier during the first state and configured to activate the differential amplifier during the second state.
    • 提供了一种读出放大器及其方法。 读出放大器分别包括耦合到第一和第二位线的第一和第二晶体管。 第一和第二晶体管被配置为在第一状态期间(例如,当差分电压存在于第一和第二位线上并且在感测信号转换之前)时将第一和第二位线连接到差分放大器并且隔离 在第二状态(例如,在感测信号转换之后)来自差分放大器的第一和第二位线。 读出放大器还包括第三晶体管,其被配置为在第一状态期间去激活差分放大器并且被配置为在第二状态期间激活差分放大器。
