The sandwich-memory-unit composes of a memory-layer, thinner than 30 nm, sandwiched between an upper and a lower barrier-layers. The barrier-layer is either an electrical conductor in case of vertical memory-cells or an electrical insulator in case of parallel memory-cells. The sandwich-memory-unit is characteristic of increased crystallization temperature of at least 50° C. as the thickness of the memory-layer is reduced from 15 to 5 nm; and the volume change of the memory-layer is less than 3% during phase change. The thickness and memory-material in each sandwich-memory-unit can be different in the multiple sandwich-memory-units. | 11-07-2013 |
