Memory element with nitrogen-containing active layer
View Patent ↗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.
1. A memory structure comprising:
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, wherein the active layer comprises a nitrogen-containing heterocycle, wherein the active layer comprises poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-alt-5,5′-(2,2′-bipyridine)].
2. A memory structure comprising:
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, wherein the active layer comprises a nitrogen-containing heterocycle, wherein the active layer comprises poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-alt-6,6″-(2,2′:6′,2″-terpyridine)].
