Patent ID: 11950430
Assignee: FERROELECTRIC MEMORY GMBH
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G  B | IPC H

Claim 11:
12. A memory cell comprising:
a first electrode;
a second electrode; and
a memory structure disposed between the first electrode and the second electrode, the first electrode, the second electrode, and the memory structure forming a memory capacitor, wherein at least one of the first electrode or the second electrode comprises:
a first electrode layer in direct contact with the memory structure, wherein the first electrode layer comprises a first electrical conductivity;
a functional layer in direct contact with the first electrode layer; and
a second electrode layer in direct contact with the functional layer, wherein the functional layer comprises a monolayer of an electrically insulating material interposed between the first electrode layer and the second electrode layer, wherein the second electrode layer has a second electrical conductivity less than the first electrical conductivity for reducing a leakage current of the memory capacitor, wherein the functional layer is disposed between the first electrode layer and the second electrode layer, and wherein the first electrode layer is not in direct contact with the second electrode layer.
