Abstract
A sense amplification device is provided. The sense amplification device includes a first sense amplifier, a second sense amplifier, and a third sense amplifier. An input terminal of the first sense amplifier is coupled to a first bit line. An input terminal of the second sense amplifier is coupled to a second bit line. The third sense amplifier has a differential input pair and a differential output pair, wherein a first input terminal of the differential input pair is coupled to an output terminal of the first sense amplifier, a second input terminal of the differential input pair is coupled to an output terminal of the second sense amplifier, a first output terminal of the differential output pair is coupled to the input terminal of the first sense amplifier, and a second output terminal of the differential output pair is coupled to the input terminal of the second sense amplifier.
