Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed an AI semiconductor device that adjusts its response characteristics to match how quickly data changes. KAIST said the team developed a programmable dynamic memtransistor and an integrated array by combining a charge storage layer and an electron trapping layer in one transistor. Experiments showed recovery time could be tuned about fivefold and frequency characteristics by more than 10-fold, cutting prediction errors by up to 40-fold in tests.

Sony has suspended operations at a key semiconductor production base in Japan\'s Kumamoto prefecture after an earthquake and has begun safety inspections of facilities. The halt has stopped a core plant that makes CMOS image sensors used in smartphones and digital cameras, raising attention on potential supply impacts. Sony has not disclosed the scale of damage or a restart schedule. The company said other production sites showed no major damage and there were no injuries.
