  • Integrated circuit with tamper-detection and self-erase mechanisms
    Patent number: 8892837
    Abstract: Methods and apparatuses for improving security of an integrated circuit (IC) are provided. A tamper condition is detected and a digital key stored in the IC is erased. The digital key is associated with a first image loaded onto the IC from a first memory. The memory may be a non-volatile memory module. A second image is loaded into a second memory module. The second memory module may be an embedded memory module, e.g., a control random access memory (CRAM) module. The first image is then erased from the first and second memory modules.
    Type: Grant
