A solid solution is a solid-state solution of one or more solutes in a solvent. Such a multi-component system is considered a solution rather than a compound when the crystal structure of the solvent remains unchanged by addition of the solutes, and when the chemical components remain in a single homogeneous phase. This often happens when the two elements (generally metals) involved are close together on the periodic table; conversely, a chemical compound generally results when two metals involved are not near each other on the periodic table.

Programmable conductor memory cell structure
In programmable conductor memory cells, metal ions precipitate out of a glass electrolyte element in response to an applied electric field in one direction only, causing a conductive pathway to grow from cathode to anode. The amount of conductive pathway growth, and therefore the programming, depends, in part, on the availability of metal ions. It is important that the metal ions come only from the solid solution of the memory cell body. If additional metal ions are supplied from other sources, such as the sidewall edge at the anode interface, the amount of metal ions may not be directly related to the strength of the electric field, and the programming will not respond consistently from cell to cell. The embodiments described herein provide new and novel structures that block interface diffusion paths for metal ions, leaving diffusion from the bulk glass electrolyte as the only supply of metal ions for conductive pathway formation.
