"Because #PoX is non‑volatile, it retains data with no standby power, a critical property for next‑generation edge AI and battery‑constrained systems. Combining ultra‑low energy with #picosecond write speeds could remove the long‑standing memory bottleneck in AI inference and training hardware, where data shuttling, not arithmetic, now dominates power budgets.
Industrial and strategic implications:
#Flashmemory remains a cornerstone of global #semiconductorstrategy thanks to its cost and scalability. #Fudan’s advance, reviewers say, offers a “completely original mechanism” that may disrupt that landscape. "

China scientists develop flash memory 10,000× faster than current tech

PoX is a new class of ultra‑fast, ultra‑green memories that meet the swelling appetite of large‑language‑model accelerators.
