SELECTOR USING SCHOTTKY DIODE OF INTERFACE WITH ELECTRODE AND PHASE CHANGE RANDOM ACCESS MEMORY INCLUDING THE SAME

摘要

Disclosed is a selection element utilizing a Schottky diode characteristic of a contact interface with an electrode and a phase change memory element comprising the same. According to an embodiment, the phase change memory element includes: a first electrode; A second electrode; A phase change material layer interposed between the first electrode and the second electrode; And the phase change material layer using a Schottky diode characteristic of a contact interface with the one electrode while being disposed between the electrode of the first electrode or the second electrode and the phase change material layer. It includes a layer of semiconductor material that acts as a selection element for.
