    摘要: A phase changeable memory element is formed by conformally forming a phase changeable material film in a contact hole on a substrate so as to create a void in the phase changeable material film in the contact hole. A capping film is formed on the phase changeable material film, and the void is at least partially closed by a thermal treatment that is sufficient to reflow the phase changeable material film in the void.

    摘要: A phase change memory device may include an integrated circuit substrate and first and second phase change memory elements on the integrated circuit substrate. The first phase change memory element may include a first phase change material having a first crystallization temperature. The second phase change memory element may include a second phase change material having a second crystallization temperature. Moreover, the first and second crystallization temperatures may be different so that the first and second phase change memory elements are programmable at different temperatures. Related methods and systems are also discussed.
