    摘要: A method of forming a memory device includes forming a first interlayer insulating layer on a semiconductor substrate, forming a first electrode in the first interlayer insulating layer, the first electrode having a top surface of a rectangular shape extending in a first direction, and forming a variable resistance pattern on the first electrode, the variable resistance pattern having a bottom surface of a rectangular shape extending in a second direction crossing the first direction, the bottom surface of the variable resistance pattern contacting the first electrode, wherein the area of contact between the lower electrode and the variable resistance pattern is substantially equal to a multiplication of a minor axis length of a top surface of the first electrode and a minor axis length of a bottom surface of the variable resistance pattern.
