The invention discloses a method for screening and matching an insulating and heat-insulating material and a nano-crystalline metal material in a nano current channel layer. The method comprises the following steps: determining the insulating and heat-insulating material according to a material selection principle; establishing a crystal model according to the insulating material, heating the crystal model to melt the crystal model, cooling the crystal model to a preset first temperature, and operating the crystal model for a preset first time to obtain an amorphous model; calculating the formation energy, mean square displacement and radial distribution function of selected nano current channel material atoms in the model according to the amorphous model; and screening a material suitable for growing and gathering in the insulating and heat-insulating material according to the formation energy, the mean square displacement and the radial distribution function. The nano current channel layer prepared from the material screened by the method is an insulating layer containing metal nano crystal grains penetrating through the film thickness of the nano current channel layer, and the current only flows between the electrode layer and the phase change layer through a nano current channel formed by the metal nano crystal grains; and the power consumption of the phase-change memory can be obviously reduced.

The invention discloses a phase change memory based on a nano current channel. A used nano current channel layer structure is used for limiting the path of a current, so that the current enters a phase change layer from a high-conductivity nano crystal grain when flowing through the layer, and the current is limited in the nano current channel. According to the nanoscale conductive channel, the contact area between the phase change layer and the electrode layer is greatly reduced, the current density of a local contact part is greatly improved, and the heat production efficiency of current in the phase change layer is improved. And meanwhile, the insulating heat-insulating material with low conductivity and low heat conductivity prevents heat in the phase change layer from being dissipated to the electrode layer, so that the electric heat utilization efficiency of the phase change layer is improved. Compared with a phase change unit which is as small as possible and manufactured by adopting a more advanced manufacturing process, the phase change memory can break through the process limitation, further reduces the effective contact area of the electrode and the phase change material, and is simple in process, so the phase change memory easily realizes the reduction of operation power consumption.
