Nikolai Yudanov 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).

  • Memory device with active and passive layers
    Patent number: 6858481
    Abstract: A memory including memory cells having active and passive layers may store multiple information bits. The active layer may include an organic polymer that has a variable resistance based on the movement of charged species (ions or ions and electrons) between the passive layer and the active layer. The passive layer may be a super-ionic material that has high ion and electron mobility. The active layer may be self-assembled from a monomer in a liquid or gas.
    Type: Grant
    Filed: April 15, 2003
    Date of Patent: February 22, 2005
    Assignee: Advanced Micro Devices, Inc.
    Inventors: Juri H. Krieger, Nikolai Yudanov
