Abstract
Semiconductor devices and methods for forming the semiconductor devices are described. An example semiconductor structure can include a substrate including a first electrode. The example semiconductor structure can further include a heater element directly contacting the first electrode in the substrate. The example semiconductor structure a phase change cell directly on the heater element. The sidewalls of the phase change cell can be encapsulated with a spacer. The example semiconductor structure a second electrode directly on the phase change cell and the spacer.
