Abstract: A neuron device is described. The neuron device is based on spontaneous polarization switching which includes a plurality of gate electrodes, a plurality of drain electrodes, a plurality of source lines, a dielectric layer, and a semiconductor layer. The gate electrodes are arranged parallel to each other. The drain electrodes are arranged parallel to each other. The source lines are arranged between the gate electrodes and the drain electrodes and parallel to each other. The dielectric layer is formed at intersections between the gate electrodes and the source lines. The semiconductor layer is formed at intersections between the drain electrodes and the source electrodes. The drain electrodes function as synapse-after-neuron linking terminals. The gate electrodes adjust an arrangement direction of electrical dipoles of the dielectric layer to control a firing time point and a firing height of the neuron device.
