Abstract

Official abstract text for this publication.

A resistance memory cell is provided and includes a first electrode, a tungsten metal layer, a metal oxide layer, and a second electrode. The tungsten metal layer is disposed on the first electrode. The metal oxide layer is disposed on the tungsten metal layer. The second electrode includes a first connection pad, a second connection pad, and a bridge portion electrically connected between the first connection pad and the second connection pad. The bridge portion is disposed on the metal oxide layer or surrounds the metal oxide layer. The resistance memory cell adjusts a resistivity of the metal oxide layer through a first current path, passing through the metal oxide layer and the tungsten metal layer, or a second current path extending from the first connection pad to the second connection pad.
