摘要： Embodiments of the invention are directed to producing spike-timing dependent plasticity using electronic neurons for computation, and pattern matching tasks such as association and recall. In response to an electronic neuron spiking, a spiking signal is sent from the electronic neuron to each axon driver and each dendrite driver connected to the spiking electronic neuron. Each axon driver receiving the spiking signal sends an axonal signal from the axon driver to a variable state resistor. Each dendrite driver receiving the spiking signal sends a dendritic signal from the dendrite driver to the variable state resistor, wherein the variable state resistor couples the axon driver and the dendrite driver. The combination of the axonal and dendritic signals is capable of increasing or decreasing conductance of the variable state resistor.
