Claim 16:
17. A variable resistance memory device, comprising:
a substrate;
memory cell structures spaced apart from each other in a first direction and a second direction on the substrate, the first and second directions being parallel to a top surface of the substrate and intersecting each other; and
a single dummy cell structure between the memory cell structures,
wherein the single dummy cell structure extends between adjacent ones of the memory cell structures that are spaced apart from each other in the first direction, and between adjacent ones of the memory cell structures that are spaced apart from each other in the second direction,
wherein each of the memory cell structures includes:
first conductive lines;
second conductive lines on and intersecting the first conductive lines; and
memory cells between the first conductive lines and the second conductive lines, and

wherein the single dummy cell structure includes:
first dummy conductive lines;
second dummy conductive lines on and intersecting the first dummy conductive lines; and
dummy memory cells between the first dummy conductive lines and the second dummy conductive lines.
