From transistor to memristor: Switching technologies for the future

https://techxplore.com/news/2022-06-transistor-memristor-technologies-future.html

"3D integration memristors allows more devices packed maintaining smallest size... new terrain for memristors... memristive technology scales up, integrating vertical, three-dimensional technology involving a nano-sized matrix of metallic wires with an insulating switch... memristor—at every junction. Applying voltage pulses breaks insulation, creating path for current flow... removing voltage, modified structure remains conductive ghost, or memory that, when voltage applied again, can be reversed"
