Title:
RESISTANCE-VARYING ELEMENT, AND INFORMATION RECORDING/REPRODUCING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/029634
Kind Code:
A1
Abstract:
Provided is a resistance-varying element comprising a resistance-varying portion including a first resistance-varying layer caused to exhibit a plurality of states of different electric resistivities by at least one of an applied voltage and an applied current, and a second resistance-varying layer caused to exhibit a plurality of states of different electric resistivities by at least one of an applied voltage and an applied current. Further comprised is an electrode layer for performing at least one of the voltage application and the current application normal to the film face of the resistance-varying portion. The resistance-varying element is characterized in that at least one of the voltage and current to transit among a plurality of different states in the first resistance-varying layer and at least one of the voltage and current to transit among a plurality of different states in the second resistance-varying layer are different from each other.
