Patent ID: 7791066

Claim:
A method for writing a first memory element and a second memory element, each of the first memory element and the second memory element comprising an insulating layer and an organic compound layer, the insulating layer and the organic compound layer provided between a first conductive layer and a second conductive layer wherein the insulating layer is provided between the organic compound layer and one of the first conductive layer and the second conductive layer, the method comprising: applying a voltage between the first conductive layer and the second conductive layer of the first memory element to melt the organic compound layer of the first memory element; and aggregating the melted organic compound layer to change conductivity of the first memory element before and after the application of the voltage, wherein data “1” is written to the first memory element by the application of the voltage, wherein the second memory element to which data “0” is written has an initial condition, and wherein the melted organic compound layer of the first memory element comprises a melted organic compound having surface tension higher than the insulating layer.
