Abstract
A method of at least one embodiment of the present invention of manufacturing a solid-state memory is a method of manufacturing a solid-state memory, the solid-state memory including a recording film whose electric characteristics are varied by phase transformation, the method including: forming the recording film by forming a laminate of two or more layers so that a superlattice structure is provided, each of the layers having a parent phase which shows solid-to-solid phase-transformation, the recording film being formed at a temperature not lower than a temperature highest among crystallization temperatures of the parent phases. It is thus possible to manufacture a solid-state memory which requires lower current for recording and erasing data and has a greater rewriting cycle number.
