Abstract :
An adaptive was developed for a synaptic connection circuit with learning ability. A synaptic weight was varied during operation when an optical correction signal was applied. The synaptic weight was varied from -0.7 to +0.7 proportionally to the applied duration of the optical correction signal and kept in a nonvolatile manner. It was clarified that artificial self-organising neural networks can be realised using the adaptive device.
