A study led by scientists from the University of Southampton’s Nano Research Group experimentally demonstrates that metal-insulator-metal devices can concurrently function as memristors, memcapacitors and meminductors.

Published in Nature’s Scientific Reports, the paper summarises that these components are concurrently modulated under voltage biasing and that meminductance is more apparent for devices of large active areas. Dr Themis Prodromakis and the team behind the study also demonstrated that the frequency response of the devices' pinched-hysteresis i-v does not follow the classical signature of memristors, and it is a manifestation of all three memory components. He believes that these features can be particularly useful in developing adaptive circuits that operate in radio-frequencies, while they open up the possibility of establishing self-resonating nanoscale components that could find applications in cellular neural networks and neuromorphic implementations.

The paper – entitled Memory Impedance in TiO2 based Metal-Insulator-Metal Devices – can be read at Nature’s Scientific Reports.
