CCTV News: Fudan University National Key Laboratory of Integrated Chip and Systems, the Research Team of the Institute of Advanced Chip and Systems, a research team recently released a semiconductor charge storage technology, which can perform 2.5 billion operations per second, which is the world's fastest semiconductor charge storage technology to date. This result has been published in the internationally renowned academic journal Nature.

The research team of Fudan University named this memory "Breaking Dawn", which is only 1 square centimeter in size, and its appearance is no different from ordinary memory. However, through innovative physical mechanisms, it increases the memory erase speed to 400 picoseconds to achieve one erase or write, and one picosecond is only equivalent to one trillionth of a second. The speed of "Dawn" is equivalent to 2.5 billion operations per second, which is 1 million times faster than traditional flash memory.

Liu Chunsen, a researcher at the National Key Laboratory of Integrated Chips and Systems, Fudan University, introduced that this speed improvement is extremely breakthrough and completely breaks a theoretical bottleneck in the existing storage technology framework.

According to reports, the team's scientific researchers have proposed a new way of speed improvement. This innovation not only achieves a huge breakthrough in speed, but also the data will not be lost in the event of power loss. After commercial applications, it is expected to promote the development of artificial intelligence computing.

The main person in charge of the scientific research team introduced that this new achievement is not far from being transformed into commercial applications. At present, the team has cooperated with the manufacturer to conduct chip verification. In the future, this technology is expected to play a huge role in artificial intelligence computing and other aspects.

Experts introduced that the computing of artificial intelligence large models mainly relies on GPU graphics chips. At present, mainstream commercial GPU chips can achieve 33.5 trillion floating-point operations per second, but the speed of writing or erasing of the accompanying memory remains at the microsecond level.

Fudan University's "Dawn" memory capability can just meet the needs of high-speed computing of GPU chips. In order to enable this breakthrough technology to achieve the results transformation as soon as possible, the research team of Fudan University has cooperated in depth with the production companies during the research and development process. It is understood that at present, the slice verification has been carried out and preliminary results have been achieved.

Liu Chunsen introduced that at present, a small-scale and full-function chip chip can be realized, and the next step can be to try to integrate it into existing mobile phones and computers. In this way, when mobile phones and computers deploy local models, they will no longer encounter some bottleneck problems caused by existing storage technologies such as lag and heating.
