  • Techniques for protecting security features of integrated circuits
    Patent number: 10657291
    Abstract: An integrated circuit includes a control circuit and a one-time programmable circuit. The control circuit determines if the one-time programmable circuit is programmed in response to an attempt to access a mode of the integrated circuit after the integrated circuit powers up. The control circuit generates a signal to indicate to a user of the integrated circuit that the mode of the integrated circuit has been previously accessed if the control circuit determines that the one-time programmable circuit has been programmed to indicate a previous access to the mode of the integrated circuit.
    Type: Grant
    Filed: September 24, 2018
    Date of Patent: May 19, 2020
    Assignee: Altera Corporation
    Inventors: Bruce Pedersen, Ting Lu, Brian Wong, Alok Doshi, Yun Sum Wong

  • Techniques for protecting security features of integrated circuits
    Patent number: 10095889
    Abstract: An integrated circuit includes a control circuit, a one-time programmable circuit, and a security feature. The control circuit determines if the one-time programmable circuit is programmed in response to a request by a user of the integrated circuit to access the security feature. The control circuit generates a signal to indicate to the user of the integrated circuit that the security feature has been previously accessed if the control circuit determines that the one-time programmable circuit has been programmed to indicate a previous access to the security feature. The control circuit causes the one-time programmable circuit to be programmed in response to the request if the control circuit determines that the one-time programmable circuit has not been programmed.
