According to a technique, an electronic device is configured to correspond to characteristic features of a biological synapse. The electronic device includes multiple bipolar resistors arranged in parallel to form an electronic synapse, an axonal 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. An increase and decrease of synaptic conduction in the electronic synapse is based on a probability of switching the plurality of bipolar resistors between a low resistance state and a high resistance state.
