UC San Diego team shows how current shapes memory in neuristors

UC San Diego researchers tracked nanoscale domain rearrangement in electrically operated vanadium-dioxide neuristors using operando coherent X-ray diffraction. Their findings show that current can change how the device learns and forgets a previous state.

UC San Diego researchers tracked nanoscale domain rearrangement in electrically operated vanadium-dioxide neuristors using operando coherent X-ray diffraction. Their findings show that current can change how the device learns and forgets a previous state.

The team examined the transition from a liquid-like mobile state to a jammed or glass-like state. According to the university, jamming the flow enables learning, while restoring free flow erases memory. This control offers an approach for research into brain-inspired computing hardware.

UC San Diego says the study appeared in Nature Communications on September 24, 2026; the university report followed on October 13. The result is a laboratory demonstration in materials physics, not an energy-consumption measurement or an already available commercial neuromorphic product.

SlackSwap combines data transfers and recomputation in GPU-limited training

Researchers at UC Merced and the University of Texas at Austin introduced SlackSwap, a planner for deep-learning training. It recomputes some activations when the transfer budget between a GPU and host memory is exceeded; reported results come from simulation, not hardware measurements.
