    摘要: A phase change random access memory (PRAM), and a method of operating the PRAM are provided. In the PRAM comprising a switching element and a storage node connected to the switching element, the storage node comprises a first electrode, a second electrode, a phase change layer between the first electrode and a second electrode, and a heat efficiency improving element formed between the first electrode and the phase change layer. The heat efficiency improving element may be one of a carbon nanotube (CNT) layer, a nanoparticle layer, and a nanodot layer, and the nanoparticle layer may be a fullerene layer.

    摘要: A phase change material, a PRAM including the same, and methods of manufacturing and operating the same are provided. Insulating impurities may be uniformly distributed over an entire or partial region of the phase change material. The PRAM may include a phase change layer including the phase change material. The insulating impurity content of the phase change material may be 0.1 to 10% (inclusive) the volume of the phase change material. The insulating impurity content of the phase change material may be adjusted by controlling the power applied to a target including the insulating impurities.
