Claim 0:
1. A semiconductor device, comprising:
first row lines each extending in a first direction;
column lines each extending in a second direction crossing the first direction;
second row lines each extending in the first direction;
a plurality of first memory cells respectively coupled between the first row lines and the column lines, each of the plurality of first memory cells including a first variable resistance layer and a first electrode positioned between the first variable resistance layer and a corresponding one of the first row lines; and
a plurality of second memory cells respectively coupled between the second row lines and the column lines, each of the plurality of second memory cells including a second variable resistance layer and a second electrode positioned between the second variable resistance layer and a corresponding one of the second row lines,
wherein the first electrode, or the second electrode, or both include a first portion and a second portion, the second portion having a nitrogen concentration higher than that of the first portion and being disposed between the first portion and a corresponding one of the first and second variable resistance layers.
