Patent ID: 8527438

Claim:
A method for producing spike-timing dependent plasticity, comprising: when an electronic neuron spikes, sending an alert pulse from the spiking electronic neuron to each electronic neuron connected to the spiking electronic neuron; when the spiking electronic neuron sends the alert pulse, sending a gate pulse from the spiking electronic neuron to each electronic neuron connected to the spiking electronic neuron; and when each electronic neuron receives the alert pulse, sending a response pulse from each electronic neuron receiving the alert pulse to the spiking electronic neuron; wherein the alert pulse notifies each electronic neuron connected to the spiking electronic neuron that the spiking electronic neuron is sending the gate pulse to said electronic neuron, and triggers said electronic neuron to read a state of said electronic neuron, wherein said electronic neuron sends a response pulse having an amplitude based on the state of said electronic neuron; wherein the response pulse is a function of time since a last spiking of the electronic neuron receiving the alert pulse; and wherein a combination of the gate pulse and response pulse is capable increasing or decreasing conductance of a variable state resistor.
