Patent ID: 8030643

Claim:
A memory device over a substrate, the memory device comprising: a first line extending in a first direction; a second line extending in a second direction perpendicular to the first direction; and a memory cell provided at an intersection of the first line and the second line, the memory cell including a memory element and a thin film transistor, wherein the memory element includes a laminated structure of a first conductive layer, an organic compound layer, and a second conductive layer, wherein the organic compound layer and the first conductive layer are in contact with each other, wherein an interface between the organic compound layer and the first conductive layer consists of a plane which is parallel to a surface of the substrate, wherein the first line is directly and electrically connected to a gate of the thin film transistor, wherein the second line is directly and electrically connected to a source region of a semiconductor layer of the thin film transistor, wherein the first conductive layer extends to and is in direct contact with a drain region of the semiconductor layer of the thin film transistor, and wherein the organic compound layer comprises a buffer layer comprising an organic compound and a metal oxide.
