Abstract
An estimation method for a variable resistance element including (i) a first electrode, (ii) a second electrode, and therebetween (iii) a variable resistance layer in which a local region is formed which has resistive status that reversibly changes according to an electric pulse applied between the first electrode and the second electrode, the estimation method including: obtaining, when changes are made to the resistive status of the local region, measurement values each indicating a resistance state after one of the changes; and determining, based on a distribution of the obtained measurement values, an estimated amount of a physical parameter regarding structural characteristics of the local region by a calculation.
