"Phase change storage cell" refers to a two terminal storage cell comprising a chalcogenide material configured to provide a detectable electrical resistance when the chalcogenide material is in crystalline state and a distinguishable electrical resistance when the chalcogenide material is in an amorphous state. In certain embodiments, a phase change storage cell may include a heater for changing the state of the chalcogenide material. In another embodiment, electric current passing through the phase change storage cell sufficiently heats the chalcogenide material to cause the phase transition from crystalline to amorphous or vice versa.In certain embodiments, the chalcogenide material may be a compound of Germanium, Antimony, and Tellurium Ge2Sb2Te5 (GST). Those of skill in the art will recognize that other forms of chalcogenide material may be used with a phase change storage cell.
