Patent ID: 8924321

Claim:
A neuron device, comprising: a bottom electrode, a top electrode, and a layer of metal oxide variable resistance material sandwiched between the bottom electrode and the top electrode, wherein the neuron device is switched to a normal state upon application of a reset voltage pulse, wherein the neuron device is switched to an excitation state upon application of a stimulus voltage pulse, wherein the neuron device is responsive to different amplitudes and/or different widths of the stimulus voltage pulse of a sequence of stimulus pulses, and provides functionalities of a weighting section and a computing section, and wherein the reset voltage pulse is a negative voltage pulse having an amplitude larger than a reset threshold V th — rest1 , the stimulus voltage pulse is a positive voltage pulse having an amplitude larger than a stimulus threshold V th — rest1 , the positive voltage pulse has a voltage drop always positive in a direction of stimulus transmission, and the negative voltage pulse has a voltage drop always negative in the direction of stimulus transmission.
