  • Publication number: 20100085798
    Abstract: A non-volatile solid state resistive device that includes a first electrode, a p-type poly-silicon second electrode, and a non-crystalline silicon nanostructure electrically connected between the electrodes. The nanostructure has a resistance that is adjustable in response to a voltage being applied to the nanostructure via the electrodes. The nanostructure can be formed as a nanopillar embedded in an insulating layer located between the electrodes. The first electrode can be a silver or other electrically conductive metal electrode. A third (metal) electrode can be connected to the p-type poly-silicon second electrode at a location adjacent the nanostructure to permit connection of the two metal electrodes to other circuitry. The resistive device can be used as a unit memory cell of a digital non-volatile memory device to store one or more bits of digital data by varying its resistance between two or more values.

  • Publication number: 20090047488
    Abstract: The present invention relates to a counterfeit prevention paper and manufacturing method thereof, and more particularly to currency, securities, official document and several certificates, etc. The counterfeit prevention paper according to the present invention comprises a paper and a thermopaint layer which is formed on a paper and is discolored according to a temperature. The counterfeit prevention paper according to the present invention can detect easily a counterfeit by an unaided eye. Also, a function for preventing a counterfeit is not copied by a counterfeit device, thus the counterfeit prevent paper according to the present invention can improve a reliability of various official documents and several certificates, etc.

  • Publication number: 20090028990
    Abstract: The present invention relates to a food composition for stimulating growth, comprising a fraction isolated from whey derived from mammalian colostrum or milk. More particularly, the present invention relates to a food composition for stimulating growth, comprising a fraction isolated from mammalian whey, wherein the fraction was removed ?-lactoalbumin and ?-lactoglobulin from the whey and had a molecular weight of 1-30 kD, as well as a method for stimulating growth, which comprises administering the food composition to mammals in need thereof, and a use of the isolated fraction for preparing the growth-stimulating food composition.

  • Publication number: 20080277719
    Abstract: The present invention relates to a non-volatile memory cell and a method of fabricating the same. The non-volatile memory cell according to the present invention comprises a substrate, a first oxide film formed over an active region of the substrate, a source and drain formed within the active region, a charge storage unit formed on the first oxide film, a second oxide film configured to surround the charge storage unit and formed on the first oxide film, and a gate formed to surround the second oxide film. According to the non-volatile memory cell and a cell array including the same in accordance with the present invention, the charge storage unit is fully surrounded by the gate or the gate line, thus a disturbance phenomenon that may occur due to the memory operation of cells formed in other neighboring gate or gate line can be minimized.
