Abstract:
1. A Phase-Change Memory (PCM), comprising: a first metal line; a second metal line; a dielectric between the first and second metal lines; a first barrier between the first metal line and the dielectric and contacting the first metal line and the dielectric; a second barrier between the second metal line and the dielectric and contacting the second metal line and the dielectric; a first memory cell having an oxide-based material including an n-type Zinc Oxide (ZnO) material in direct contact with a natural p-type crystalline PCM material to form a diode junction embedded in the PCM material, the ZnO material contacting the first metal line; first material arranged in a stack with the ZnO material and the PCM material; a second memory cell having an oxide-based material including an n-type ZnO material in direct contact with a natural p-type crystalline PCM material to form a diode junction embedded in the PCM material, the ZnO material contacting the second metal line; and a second material arranged in a stack with the ZnO material and the PCM material of the second memory cell.
