  • Patent number: 8426841
    Abstract: The present invention relates to a transparent memory for a transparent electronic device. The transparent memory includes: a lower transparent electrode layer that is sequentially formed on a transparent substrate, and a data storage region and an upper transparent layer which are made of at least one transparent resistance-variable material layer. The transparent resistance-variable material layer has switching characteristics as a result of the resistance variance caused by the application of a certain voltage between the lower and upper transparent electrode layers. An optical band gap of the transparent resistance-variable material layer is 3 eV or more, and transmittivity of the material layer for visible rays is 80% or more. The invention provides transparent and resistance-variable memory that: has very high transparency and switching characteristics depending on resistance variation at a low switching voltage, and can maintain the switching characteristics thereof after a long time elapses.
