摘要: An object of the present invention is to provide a technique for suppressing thermal disturbance of a phase change memory device having a three-dimensional structure. In the phase change memory device having a three-dimensional structure, a material having a high thermal conductivity is used as a gate insulation film of a MOS transistor for selection, and causes heat transmitted to a Si channel layer from a phase change recording film to successfully diffuse to a gate electrode. In this way, since heat generated from a recording bit diffuses to a non-selected bit adjacent to it, it is possible to suppress thermal disturbance. BN, Al2O3, AlN, TiO2, Si3N4, ZnO and the like are useful as a gate insulation film having a high thermal conductivity.

摘要: There is provided a semiconductor storage device which is capable of further reducing a size of a memory cell, and increasing a storage capacity. Plural memory cells each including a transistor formed on a semiconductor substrate, and a variable resistive device having a resistance value changed by voltage supply and connected between source and drain terminals of the transistor are arranged longitudinally and in an array to configure a three-dimensional memory cell array. A memory cell structure has a double channel structure in which an inside of a switching transistor is filled with a variable resistance element, particularly, a phase change material. The switching transistor is turned off by application of a voltage to increase a channel resistance so that a current flows in the internal phase change material to operate the memory.
