Abstract
An electronic device includes a semiconductor memory. The semiconductor memory includes first and second lower plugs, a first pad, a second pad, a first lower line, a second lower line, a first insulation pattern, a second insulation pattern, an upper plug, an upper line, and a plurality of variable resistance elements disposed at regions where the first and second lower lines overlap the upper line.
Claims17
An electronic device comprising a semiconductor memory, wherein the semiconductor memory comprises:
- first and second lower plugs disposed over a substrate;
- a first pad disposed over the first lower plug;
- a second pad being spaced apart from the first pad in the first direction;
- a first lower line extending from the first pad, being disposed between the first pad and the second pad in the first direction, and having a smaller width than the first pad in a second direction crossing the first direction;
- a second lower line extending from the second pad, being disposed between the first pad and the second pad in the first direction, being spaced apart from the first lower line in the second direction, and having a smaller width than the second pad in the second direction;
- a first insulation pattern disposed between the first lower line and the second pad, the first insulation pattern being in contact with an end of the first lower line;
- a second insulation pattern disposed between the second lower line and the first pad, the second insulation pattern being in contact with an end of the second lower line;
- an upper plug disposed over the second lower plug;
- an upper line traversing first lower line and the second lower line, being coupled to the upper plug, and extending in the second direction;
- and
- a plurality of variable resistance elements disposed at regions where the first and second lower lines overlap the upper line.
