Abstract
A sense amplifier of a memory device that includes sense amplifier circuits and a reference sharing circuit is introduced. The sense amplifier circuits are configured to sense the plurality of bit lines according to an enable signal. The reference sharing circuit includes first switches and second switches that are coupled to the reference nodes and second reference nodes of the sense amplifier circuits, respectively. The first switches and second switches are controlled according to a control signal to control a first electrical connection among the first reference nodes, and to control a second electrical connection among the second reference nodes. An operation method of the sense amplifier and a memory device including the sense amplifier are also introduced.
