Michael Coey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Frequency resistance access magnetic memory
    Patent number: 9208846
    Abstract: The invention provides a multibit magnetic memory structure comprising a stack of two or more magnetic plaquettes, each of which has at least three distinct magnetic states. The invention provides for a new type of vertical memory where each layer encodes information in two degrees of freedom, which has the potential to increase the theoretical storage capacity by factor 4n. The information is read, through the resonant frequency of the stack or through a combination of the resonant frequency and resistance.
    Type: Grant
