Abstract
A current sensing circuit including a differential sensing amplifier and a pre-charging circuit is provided. The differential sensing amplifier includes a first input end, a second input end and a output end. The first input end is coupled to a selected cell via a first data line. The second input end is coupled to a reference cell via a second data line. The output end outputs a sensing data of the selected cell. The pre-charging circuit is coupled to the differential sensing amplifier. The pre-charging circuit is configured to provide a pre-charging circuit and perform a pre-charging operation on the first data line. The first data line has a cell current and the pre-charging circuit. The second data line has a reference current. The pre-charging circuit is determined according to the reference current.
