The credit for the first functional memristor goes to the Hewlett-Packard Company—in particular, researchers R. Stanley Williams, Dmitri B. Strukov, Gregory S. Snider, and Duncan R. Stewart—for building a bi-level titanium dioxide thin film containing dopants (impurities) on one side that migrate to the other side when a current is applied and back when the opposite current is applied, changing the resistance in each case. Hewlett-Packard is working on incorporating memristors into traditional integrated circuits. https://www.britannica.com/technology/memristor https://www.britannica.com/technology/memristor
