Chemical oscillator networks enable physical information storage. We built a memory block from four photosensitive Belousov–Zhabotinsky oscillators with adaptive inhibitory coupling. Artificial synapses allow external control and Hebbian-like self-tuning, creating stable memory states. Experiments map collective modes and reveal bistable and multistable domains with controllable switching. Simulations confirm transition sequences and show that memory depends mainly on coupling strength and plasticity, while delays influence timing. This demonstrates a tunable chemical memory for neuromorphic computing.
