Monolithic three-dimensionally integrated memristor-thin-film transistor for electrically programmable multimode reservoir computing

Reservoir computing offers an efficient framework for processing temporal information, but most hardware reservoirs exhibit fixed or narrowly tunable dynamics determined by intrinsic material relaxation time. A monolithically integrated memristor-thin-film transistor reservoir ke...

Fast Electronic Memristors with Improved Retention and Synaptic Functionality Enabled by Tri-TaOx Engineering

Artificial synaptic memristors require fast switching, stable retention, low variability, and linear conductance modulation, but achieving these properties simultaneously is difficult in electronic bipolar resistive switching (e-BRS) devices. In this study, a tri-TaOx memristor i...

Memristive Motion‐Streak Neuron for Spatiotemporal Multiple Object Detection

ABSTRACT Conventional artificial vision systems process dynamic scenes inefficiently by reconstructing motion from discrete frames, which requires post‐processing. In contrast, real‐world environments containing multiple moving objects demand sensor‐level discrimination. This wor...
