Recently, a notable breakthrough has been achieved by the research group helmed by Professor Zhongrui Wang of the School of Microelectronics at the Southern University of Science and Technology (SUSTech). In a collaborative effort with Researcher Dashan Shang and Researcher Xiaoxin Xu, hailing from the team led by Academician Ming Liu at the Institute of Microelectronics, Chinese Academy of Sciences, the team has made substantial strides in the realm of in-memory data pruning and computation tailored for brain-inspired edge vision systems.

Leveraging a standard CMOS-compatible process, the research team successfully developed a multifunctional Mem-Selector (M-S) nano-device, characterized by its Ta/TaOx/Ta₂O₅ structure. Building upon this innovation, they constructed a brain-inspired in-memory pruning-computation (IMPC) system, utilizing a 32×32 (1 Kb) M-S array as its foundation.
