    摘要: Provided is a resistance variable memory device and a method for operating same. The resistance variable memory device has a phase change material between a top electrode and a bottom electrode. In the method for operating a resistance variable memory, the write current is applied in a direction from the top electrode to the bottom electrode, and the read current is applied in a direction from the bottom electrode to the top electrode. The phase change material is programmed by applying the write current, and a resistance drift of the phase change material is restrained by applying the read current.

    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.
