1. A control device for controlling a sense amplifier, comprising:
a latch circuit, receiving a plurality of memory data signals from the sense amplifier, wherein the latch circuit respectively generates a plurality of reference data signals based on the plurality of memory data signals; and
a control circuit, coupled to the latch circuit, providing an enable signal to the sense amplifier in response to a pass gate signal of the sense amplifier, and stops providing the enable signal in response to at least one of the plurality of reference data signals, wherein the enable signal controls a sensing period of the sense amplifier.
