NONVOLATILE STORAGE DEVICE AND MANUFACTURING METHOD FOR THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide an easily processable nonvolatile storage device having excellent operating characteristics, and also to provided a manufacturing method for the same. Ž<P>SOLUTION: The nonvolatile storage device has following parts on a substrate: a first wiring extending in a first direction; a second wiring extending in a second direction not parallel to the first direction; and a recording layer sandwiched between the first wiring and the second wiring so as to be reversibly shiftable between a first state and a second state by a current supplied via the first wiring and the second wiring. The recording layer has an inversely tapered shape in which a cross section parallel to the first/second directions becomes gradually larger as it goes close to the second wiring.
