Abstract: A circuit structure and a driving method thereof, a neural network are disclosed. The circuit structure includes at least one circuit unit, each circuit unit includes a first group of resistive switching devices and a second group of resistive switching devices, the first group of resistive switching devices includes a resistance gradual-change device, the second group of resistive switching devices includes a resistance abrupt-change device, the first group of resistive switching devices and the second group of resistive switching devices are connected in series, in a case that no voltage is applied, a resistance value of the first group of resistive switching devices is larger than a resistance value of the second group of resistive switching devices. The circuit structure utilizes a resistance gradual-change device and a resistance abrupt-change device connected in series to form a neuron-like structure, so as to achieve to simulate functions of a human brain neuron.
