ABSTRACT:
A neuron element with electrically programmable synaptic weight for an artificial neural network features an excitatory-connection floating-gate transistor and an inhibitory-connection floating-gate transistor. The control gate electrodes of the two transistors are connected together, and the drain electrode of the inhibitory-connection transistor is connected to the source electrode of the excitatory-connection transistor. Both of the excitatory-connection and inhibitory-connection transistors have programming electrodes. The control gate electrodes and the programming electrodes can be utilized to program the threshold voltages of the transistors and thus the synaptic weight of the neuron element.
