Tech News Digest: Hydrogen AI Chips, NVIDIA's AV Push, and Open-Source Security
Breakthrough Hydrogen-Based AI Chip Mimics Human Brain for Self-Learning A research team from the Daegu Gyeongbuk Institute of Science and Technology (DGIST) has developed the world’s first two-terminal artificial intelligence semiconductor that utilizes hydrogen ions for self-learning and memory. This innovative technology precisely controls hydrogen ion injection and discharge with electrical signals, emulating the human brain’s ability to perform computation and storage simultaneously. Unlike conventional oxide-based memory devices that suffer from stability issues due to oxygen vacancies, this hydrogen-based approach resolves speed degradation and high power consumption in modern AI data processing. The neuromorphic semiconductor operates by changing its conductivity based on electrical signals and maintaining that state, similar to an artificial synapse. This breakthrough was achieved in a two-terminal vertical structure, which is advantageous for high-density AI chips due to its potential for high integration and simple manufacturing. The device has demonstrated high reliability, successfully running for over 10,000 repetitive operations. ...
