Abstract
A memory, system, and method to improve integration density while maintaining thermal efficiency through a phase change memory cell with a superlattice based thermal barrier. The phase change memory may include a bottom electrode. The phase change memory may also include an active phase change material. The phase change memory may also include a superlattice thermal barrier proximately connected to the active phase change material. The phase change memory may also include a top electrode proximately connected to the superlattice thermal barrier. The system may include the phase change memory cell. The method for forming a phase change memory may include depositing an active phase change material on a bottom electrode. The method may also include depositing a superlattice thermal barrier proximately connected to the active phase change material. The method may also include depositing a top electrode proximately connected to the superlattice thermal barrier.
