  • Patent number: 11960608
    Abstract: A method to secure boot an electronic device is disclosed according to some embodiments. The method includes receiving a request to initiate a boot sequence using memory content stored in a non-volatile memory circuit. A secure boot circuit receives verification data from the non-volatile memory circuit indicating the memory content. The verification data includes an error correction code for the memory content without including all of the memory content. A cryptographic hashing operation is performed to the error correction code in the secure boot circuit to obtain a digest of the error correction code.
