3D neuromorphic prototype reportedly tunes memory timescales across about three orders of magnitude

An October 5 science roundup says Seoul National University and Yonsei researchers built a 3D neuromorphic prototype with electrically tunable memory timescales spanning about three orders of magnitude. It describes stacked memristors and thin-film transistors used to demonstrate motion and ultrasound classification. Peripheral power use, device variation, endurance and manufacturing yield still need verification; it is not a commercial AI chip.
