| 摘要 |
A structure including a phase change material and a related method are disclosed. The structure may include a first electrode; a second electrode; a third electrode; a phase change material electrically connecting the first, second and third electrodes for passing a first current through two of the first, second and third electrodes; and a refractory metal barrier heater layer about the phase change material for converting the phase change material between an amorphous, insulative state and a crystalline, conductive state by application of a second current to the phase change material. The structure may be used as a fuse or a phase change material random access memory (PRAM).
