Abstract

The present memory structure includes first and second electrodes, a passive layer, and an active layer containing nitrogen, the passive and active layers being between the first and second electrodes. Metal ions in the active layer bind to the nitrogen thereof, enhancing retention of the metal ions in the active layer for improved, stable data retention.
