| Outline of Final Research Achievements |
In order to improve the performance of intelligent information processing devices and systems that have been developed using silicon transistors, research on artificial intelligence using ionic conductors has attracted much attention. In this study, a system using several artificial synaptic devices with ionic conductors, such as silver sulfide and tantalum oxide films, have been constructed and verified their operation. It was confirmed that differences in film density and composition of ionic conductors affect the response characteristics of the synaptic circuit.
