The present invention relates to a variable resistance memory device and a method for forming the same. A variable resistance memory device according to the present invention includes a first electrode; a second electrode spaced apart from the first electrode; a resistance variable layer and a metal-insulator transition layer provided between the first electrode and the second electrode; and a heat barrier layer provided (i) between the first electrode and the metal-insulator transition layer, (ii) between the metal-insulator transition layer and the resistance variable layer, or (iii) between the second electrode and the metal-insulator transition layer. The present invention prevents dissipation of heat generated in the metal-insulator transition layer using a thermal boundary resistance (TBR) phenomenon, and thus current and voltage to operate the variable resistance memory device can be reduced. |
