  • Patent number: 10559542
    Abstract: Various methods and structures for fabricating a semiconductor chip structure comprising a chip identification “fingerprint” layer. A semiconductor chip structure includes a substrate and a chip identification layer disposed on the substrate, the chip identification layer comprising random patterns of electrically conductive material in trenches formed in a semiconductor layer. The chip identification layer is sandwiched between two layers of electrodes that have a crossbar structure. A first crossbar in the crossbar structure is located on a first side of the chip identification layer and includes a first set of electrical contacts in a first grid pattern contacting the first side of the chip identification layer. A second crossbar in the crossbar structure is located on a second side of the chip identification layer and includes a second set of electrical contacts in a second grid pattern contacting the second side of the chip identification layer.

  • Publication number: 20180160308
    Abstract: Embodiments are directed to a method of providing access verification for a system that includes activating a security control device, which is in communications with a host device. The method also includes having the security control device receiving a verification signal coming from outside the system while being locally-based, and comparing the verification signal to a table of stored criteria values. The device then chooses a response based on that comparison and sends an access determination signal based on the response.
