Simplification of Processing Elements in Cellular Neural Network

We have succeeded in simplification of processing elements in cellular neural network. First, we reduce a neuron to two-inverter two-switch circuit, two-inverter one-switch circuit, or two-inverter circuit. Next, we reduce a synapse only to one variable resistor or one variable capacitor. Finally, we confirm the correct operation of the cellular neural network by learning of arbitrary logics. These results will be theoretical bases to realize ultra-large scale integration for brain-type integrated circuits.
