Description
Bohao Ding and colleagues merge two memory styles in one tiny device for brain-like computing in a 2026 study. Their nanoporous silica memristor can hold a state briefly or keep it long-term, switched simply by tuning the current limit. Clear ion paths inside the pores let filaments form and dissolve in a controlled way.
Used as a physical reservoir, the fleeting states processed signals while stable states served as readout weights. The system reached 93.7% accuracy on handwritten digit recognition in benchmark tests and over 88% accuracy when sorting normal from abnormal heartbeat patterns in ECG tests. One CMOS-friendly material doing both jobs could shrink low-power smart hardware.
