Abstract The recent revision of the International System of Units (SI)—which fixed the numerical values of nature’s fundamental constants—has opened new perspectives for practical realizations of SI units. Here we demonstrate an intrinsic resistance standard based on memristive nanoionic cells that operate in air at room temperature and are directly accessible to end users.

The memristor has been the topic of heated research activity since the Platinum/TiO2/TiOx/Platinum structure was reported by Hewlett-Packard Labs. The characteristics of memristors such as the pinched hysteresis loops and time and input signal dependent memristance are due to the drift of positively charged oxygen vacancies in the TiOx layer.
