Sub‑10 ms Phase‑Change Memristor Chip Accelerates Brain Cortex Reconstruction by 480×
A team from Peking University and the Chinese Academy of Sciences built a 40 nm neural dynamical system chip that leverages phase‑change memristor conductance drift for adaptive step‑size search and compute‑in‑memory, cutting iteration latency to 2.12 ms and achieving up to 480‑fold faster cortical surface reconstruction compared with GPU A100, while reducing power consumption by up to 24.7×.
