PROBLEM TO BE SOLVED: To provide a data storage device (100) having a laminated memory layer whose reliability is superior to that of a conventional technology. SOLUTION: This data storage device (100) includes: a lamination having at least one memory layer (106), the memory layer having a plurality parts in which data are stored by changing the physicochemical identity of a substance forming the plurality of parts while a current flows through the plurality of parts; and a plurality of photoconductivity columns (110) which are arranged within the lamination and penetrate each layer in the lamination. Each of the plurality of parts of the memory layer surrounds one of the photoconductivity columns. COPYRIGHT: (C)2010,JPO&INPIT |
