Claim Text:
1. An electronic device comprising a semiconductor memory unit, the semiconductor memory unit comprising: a first electrode formed over a substrate, having a first end and a second end at a distance in a first direction from the first end, and receiving a voltage through the first end; a plurality of resistance variable layers, each formed along a side of the first electrode to be thinner going from the first end to the second end; a plurality of second electrodes each formed adjacent to the first electrode and separated from each other along the first direction, a corresponding one of the resistance variable layers being disposed between each second electrode and the first electrode; and a plurality of insulation layers, each separating and isolating adjacent second electrodes and adjacent resistance variable layers, wherein the adjacent resistance variable layers are insulated from each other by a corresponding one of the plurality of insulation layers.
