Abstract:
The inventive concept provides a memory device, in which memory cells are arranged to have a low variation in electrical characteristics and thereby enhanced reliability, an electronic apparatus including the memory device, and a method of manufacturing the memory device. In the memory device, memory cells at different levels may be covered with spacers having different thicknesses, and this may control resistance characteristics (e.g., set resistance) of the memory cells and to reduce a vertical variation in electrical characteristics of the memory cells. Furthermore, by adjusting the thicknesses of the spacers, a sensing margin of the memory cells may increase.

Claim (Index 18):
A memory device, comprising:\n a first electrode line provided on a substrate, the first electrode line extending in a first direction; a second electrode line provided on the first electrode line, the second electrode line extending in a second direction different from the first direction; a third electrode line provided on the second electrode line, the third electrode line extending in the first direction; a first memory cell provided at an intersection of and between the first and second electrode line layers, the first memory cell comprising a first selection device, a first electrode, and a first variable resistance pattern stacked in a vertical direction; a second memory cell provided at an intersection of between the second and third electrode line, the second memory cell comprising a second selection device, a second electrode, and a second variable resistance pattern stacked in the vertical direction; a first spacer covering side surfaces of the first memory cell; and a second spacer covering side surfaces of the second memory cell, wherein an inner spacer covers side surfaces of at least one of the first selection device and the second selection device, and the inner spacer is covered by at least one of the first spacer and the second spacer.
