Recently, the research team helmed by Professor Yang Yuchao—a New Cornerstone Investigator, Dean of the School of Information Engineering at Peking University Shenzhen Graduate School, and Director of the Guangdong Provincial Key Laboratory of In-Memory Computing Chips—worked in tandem with the team led by Researcher Song Zhitang from the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences. Their collaborative efforts culminated in the publication of their groundbreaking research findings, titled "A sub-10-millisecond neural dynamical system based on phase change memristors", in the prestigious journal 'Science'.

The team successfully pioneered the world's inaugural neurodynamic system chip grounded in phase change memristors, marking a historic reduction in the single-step operation latency of the neurodynamic system to a mere 2.12 milliseconds for the first time. In tasks such as cortical reconstruction, this innovative chip demonstrated remarkable speed enhancements, ranging from 50 to 478 times faster than current state-of-the-art graphics processing units (GPUs). This breakthrough effectively shattered the real-time computing bottleneck that has hindered neurodynamics for half a century.

Leveraging a 40-nanometer process, the chip attains a single-iteration latency of 2.12 milliseconds, thereby unlocking fresh avenues in domains such as brain-computer interfaces and the diagnosis and treatment of brain diseases.
