Abstract
A memory device having a vacuum jacket around the first electrode element for improved thermal isolation. The memory unit includes a first electrode element; a phase change memory element in contact with the first electrode element; a dielectric fill layer surrounding the phase change memory element and the first electrode element, wherein the dielectric layer is spaced from the first electrode element to define a chamber between the first electrode element and the dielectric fill layer; and wherein the phase change memory layer is sealed to the dielectric fill layer to define a thermal isolation jacket around the first electrode element.
