USTC Develops Sensing-Memory-Computing Integrated Photodiode

A research team led by Professor Sun Haiding from the School of Integrated Circuits at the University of Science and Technology of China (USTC), in collaboration with multiple universities both domestically and internationally, has successfully developed the world’s first photodiode that integrates optical sensing, storage, and processing functions into a single device.

The device’s fabrication process is highly compatible with existing silicon-based semiconductor microfabrication techniques. This breakthrough not only offers a new approach to addressing the high power consumption and data latency issues of traditional visual sensors but also provides a promising hardware solution for the development of next-generation low-power edge computing vision terminals, neuromorphic computing chips, and intelligent machine vision systems.
