HYBRID ELECTRONIC-IONIC CIRCUIT FOR IMPLEMENTING A BIO-PLAUSIBLE THREE-FACTOR SYNAPTIC PLASTICITY RULE

Abstract: disclosed herein is a hybrid electronic-ionic circuit comprising a first electrochemical ionic synapse (eis), wherein in response to a non-zero electrical stimulus applied to the first eis, the first eis operates in a volatile operation mode to generate a delayed-onset self-resetting signal; and a second eis, wherein in response to a non-zero electrical stimulus applied to the second eis, the second eis operates in a non-volatile operation mode and a conductance of the second eis controls a strength of an output of the second eis. in some embodiments, the non-zero electrical stimulus for the first eis comprises one or more of a context signal or a variability signal. in some embodiments, the non-zero electrical stimulus for the second eis comprises one or more of the delayed-onset self-resetting signal, a reward signal, or a context signal.
