New candidate for universal memory is fast, low-power, stable and long-lasting

https://techxplore.com/news/2024-01-candidate-universal-memory-fast-power.html

"nonvolatile (can retain state 10+ years) phase-change memory made from GST467 alloy 4 parts germanium, 6 parts antimony, and 7 parts tellurium, sandwiched in-between as part of nano- superlattice... fast (switching at few tens of ns), low-power (<1 V), stable, compact (<40 nm diameter), fabricated at temperatures compatible with commercial manufacturing... bring memory and processing closer together in 1 device... AI and data-centric systems, long-term storage... future: stacking in 1000's of layers"
