Volatile Memristive Devices With Tunable Temporal Dynamics For Event-Based Sensing

First published: 30 August 2026

Tunable volatile memristive devices can serve various neural-inspired tasks that require different time windows of information retention. The ionic-based volatility of the presented Pt/a-STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.
The device's programmable temporal dynamics are exploited for event-based vision applications, with the wide span of decay time constants enabling applicability across multiple sensory modalities.
