South Korean Team Validates Synaptic Transistor for AI Chips in Space Environments

A South Korean research team confirmed that a synaptic transistor can be applied in high-radiation space environments. The project, involving the Korea Atomic Energy Research Institute, Chungbuk National University, and IMEC, was funded by the Ministry of Science and ICT. The transistor, made from indium-gallium-zinc oxide, withstood radiation equivalent to 20 years in space, showing stable core functions despite some performance degradation. This marks a significant step towards developing space-grade AI semiconductors.
