Photoelectric-motivated memristor to realize single nerve synapse

Nowadays, memristors are one of the most important ways to realize the nerve synapse. Memristors agree quite well with biological synapses, because they has an electrical resistance that changes from external application conditions. In this paper, we present a theory of the memristive principle of photoelectric-motivated memristors. And the photoelectric-motivated memristor is simulated to have the function of a biological synapse, including synaptic weights, spike-timing-dependent plasticity function, long-term and short-term plasticity, paired-pulse facilitation, and peak-dependent synaptic plasticity. Based on the actual test circuit, the weight of the synapse is adjustable. The photoelectric-motivated memristor provides a direction for the large-scale integration and application of light-controlled electronic synapses in CMOS technology.
