The article discusses phase-change memory (PCM) as a promising innovation in non-volatile memory technology, particularly for AI workloads and neuromorphic computing. PCM, leveraging chalcogenide glass and superlattice materials, offers significant potential for energy-efficient, high-speed, and high-density data storage, though it still faces challenges in scalability and industry adoption. The article also highlights a collaboration between electrical and computer engineers at Stanford University and the University of California at San Diego that attempts to understand the advantages of neuromorphic applications. Recent breakthroughs in PCM, including low-power operation and nanoscale fabrication, could lead to widespread applications in brain-inspired computing and in-memory processing, but commercialization hurdles remain.
