Abstract
A sensing circuit is provided which generates a sensing result according to a reading voltage of a non-volatile memory. The sensing circuit includes four transistors and a switch group. A first transistor is coupled between an operating voltage and a first node. A second transistor is coupled between the first node and a second node. A third transistor is coupled between the second node and a reference ground voltage. A control terminal of the first transistor, a control terminal of the second transistor, and a control terminal of the third transistor all receive the reading voltage. A fourth transistor is coupled between the operating voltage and the first node. The switch group forms or disconnects a conduction path between a control terminal of the fourth transistor and the second node according to a control signal, so that the first node obtains the sensing result.
