Patents by Inventor NORMAN O. BIRGE

NORMAN O. BIRGE 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).

  • Josephson magnetic memory cell system
    Patent number: 9013916
    Abstract: One aspect of the present invention includes a Josephson magnetic memory system. The system includes a superconducting electrode that conducts a read current. The system also includes a hysteretic magnetic Josephson junction (HMJJ). The HMJJ can store a binary value and convert superconducting pairs associated with the read current flowing through the HMJJ from a singlet-state to a triplet-state. The system further includes a write circuit magnetically coupled to the HMJJ and configured to write the binary value into the at HMJJ in response to at least one write current and a read circuit configured to determine the binary value stored in the HMJJ in response to application of the read current to the HMJJ.
    Type: Grant
