Patent ID: 11296148

Abstract:
A variable resistance memory device including a substrate; first and second transistors on the substrate; first conductive lines on the transistors, each of the first conductive lines extending in a first direction, and the first conductive lines being spaced apart from each other; first contact plugs directly contacting substrate-facing surfaces of the first conductive lines, the first contact plugs being electrically connected to the first transistors, respectively; second conductive lines on the first conductive lines, each of the second conductive lines extending in the second direction, and the second conductive lines being spaced apart from each other; second contact plugs directly contacting substrate-facing surfaces of the second conductive lines, the second contact plugs being electrically connected to the second transistors, respectively; and memory units between the conductive lines, wherein each of the second contact plugs does not overlap with any of the memory units in the third direction.
