a Digital to Analog Circuit (DAC) is utilized to provide SET and READ voltage to the synapse. A Winner-Take-All (WTA) circuit is used to determine the maximum current contained columns from all active columns. A current-controlled synaptic circuit is presented at the right of the synaptic array. Three thick oxide transistors and a HfO2 based memristor are utilized to construct the synapse. b Shows the configuration for a neuroprocessor. Peripheral circuits control the gate of the synapse and read currents are sent to the LIF neuron.
