In recent years, the development of artificial synaptic devices has gained momentum in the field of neuromorphic computing. Memristors are currently attracting attention as a candidate for such synaptic devices. Reduced titanium dioxide (TiO2-x) is a promising material for creating memristor devices. We have previously developed TiO2-x four-terminal planar memristors using single-crystals and epitaxial thin films. By gate modulation of the oxygen vacancy distribution in TiO2-x with two of the four terminals, advanced heterosynaptic functionality realizing synaptic properties, such as tunable spike-timing-dependent plasticity and synaptic plasticity mimicking habituation and sensitization, etc., has been demonstrated.
In this study, we developed a miniaturized device structure that will enable high integration in the future, and verified the possibility of multi-element integration and dimensional extension by bidirectional Pavlovian conditioning.
