Science Tokyo builds 25-nanometer memory chip that improves as it gets smaller

Researchers at Science Tokyo created a 25-nanometer memory device that improves as it gets smaller, defying the conventional trade-off where miniaturization increases energy loss. Published in the journal Nanoscale (Royal Society of Chemistry) as a front cover feature, the device stores information as 0s and 1s by controlling electrical conductivity with far less power than conventional memory. The finding challenges the assumption that miniaturization necessarily creates a trade-off between size and energy efficiency, and could dramatically reduce energy demands of phones, computers, and AI hardware.
