Negative Feedback in Hf0.5Zr0.5O2 Resistive Memory: Feigenbaum Route Toward Two‐Terminal Pseudo‐Random Number Generation and Neural Network Instabilities

open access: yesAdvanced Electronic Materials, EarlyView.
Resistively switching TiN/Hf0.5Zr0.5/Au valance‐change memory devices show period‐doubling bifurcations, arising from competing influences of filamentary counter‐eightwise filamentary switching and eigthwise electrochemical oxygen exchange at the active electrode.
