Structural Engineering of Li-Based Electronic Synapse for High Reliability

In this study, a highly reliable Li based two-terminal electrochemical synapse device was developed to investigate the synaptic characteristics. Based on the identified fabrication conditions, a solid-state electrolyte was interposed between the anode and cathode to prevent the self-injection phenomenon. Consequently, improved reliabilities, such as endurance and retention, were achieved. These results demonstrate the significant potential of two-terminal synaptic device in the hardware implementation of neuromorphic computing systems.
