Zusammenfassung:Methods for fabricating highly compact PCM memory devices are described herein. The methods may include forming a bipolar junction transistor (BJT) structure on a substrate including creating a base of the BJT structure on the substrate and creating an emitter of the BJT structure on top of the base opposite of the substrate. A heating element may then be constructed on the emitter of the BJT structure, wherein the heating element includes a material to generate heat when provided with an electrical current from the emitter. A phase change material (PCM) cell may then be built on the heating element opposite of the BJT structure.
