Abstract
The electrode of a phase change memory may be formed with a mixture of metal and a non-metal, the electrode having less nitrogen atoms than metal atoms. Thus, in some embodiments, at least a portion of the electrode has less nitrogen than would be the case in a metal nitride. The mixture can include metal and nitrogen or metal and silicon, as two examples. Such material may have good adherence to chalcogenide with lower reactivity than may be the case with metal nitrides.
