Abstract
The PCM cell includes a phase-change material layer (or PCM layer, for short), e.g., a layer including a germanium-antimony-tellurium alloy. The PCM layer has a top surface, a bottom surface, and a side surface linking the top surface and the bottom surface. The PCM cell further includes an outer electrode, which contacts the side surface of the PCM layer. That is, the outer electrode laterally caps the PCM layer. The PCM cell further includes a heater extending at least partially through the PCM layer, transversely to the top surface and the bottom surface of the PCM layer, to contact the PCM layer.
