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. The digest is compared with a pre-stored reference digest to generate a verification signal. The verification signal is provided to the electronic device indicating whether the boot sequence passes the verification.
