Abstract
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.
