A neural-like circuit includes a synaptic circuit and a posterior neuron circuit. The synapse circuit comprises a phase change element, a first switch and a second switch. The phase change element comprises a first end and a second end. The first switch comprises a first end and a second end. The second switch comprises a first end, a second end and a control end. The first switch is used for receiving a first pulse signal. The second switch is coupled to the phase change element and the first switch. The second switch is used for receiving a second pulse signal. The rear neuron circuit comprises a capacitor and an input end. The input end of the rear neuron circuit responds to the first pulse signal to charge the capacitor. The rear neuron circuit generates an excitation signal accordingto the voltage level of the capacitor and a voltage threshold value. The rear neuron circuit generates a control signal according to the excitation signal. The control signal controls the second switch to be switched on, and
