How do STM32H753XIH6 and STM32L4S7AII6 verify memory contents?

Hello, does anyone know how these two components (STM32H753XIH6 and STM32L4S7AII6) verify that the data in both internal and external memories(Ram, Rom, Nor and Nand) are not corrupted?

Thanks for your help?

    Hello @Alex12 and welcome to the community,

    In H7, the mechanism to check the memory consistency is the ECC either in internal RAM (RAM ECC) or the internal flash memory. For external memory only NAND mode is supporting ECC.

    Refer to the AN5342 "How to use error correction code (ECC) management for internal memories
    protection on STM32 MCUs "
