1. A differential sensing circuit with a dynamic voltage reference for a single-ended bit line memory, the differential sensing circuit comprising: a dynamic voltage reference generating unit, coupled to an input voltage, for receiving a setting signal to generate the dynamic voltage reference; and a differential sensing amplifying unit, coupled to the single-ended bit line memory and the dynamic voltage reference generating unit, for receiving at least an input signal from the single-ended bit line memory and the dynamic voltage reference from the dynamic voltage reference generating unit, so as to generate at least an output signal accordingly.
