Abstract:
1. An electronic device configured to correspond to characteristic features of a biological synapse, the electronic device comprising: a plurality of bipolar resistors arranged in parallel to form an electronic synapse, wherein the plurality of bipolar resistors each have a required switching voltage to switch from one state to another; an axon connection connected to one end of the electronic synapse and to a first electronic neuron; and a dendritic connection connected to another end of the electronic synapse and to a second electronic neuron; wherein the plurality of bipolar resistors each have voltages on the axon and dendritic connections that cause a resultant voltage below the required switching voltage for the plurality of bipolar resistors; and wherein an increase and decrease of synaptic conduction in the electronic synapse is based on an effective probability of switching the plurality of bipolar resistors between a low resistance state and a high resistance state; wherein the resultant voltage for each of the plurality of bipolar resistors is defined as a resultant waveform, in which a first part, being positive, of the resultant waveform corresponds to a first probability of switching to an on state and in which a second part, being negative, of the resultant waveform corresponds to a second probability of switching to an off state.
