Web29 de mai. de 2024 · It seems, that the ECC is calculated and persisted per 32-bit word. If so, the ECC must have a length of at least 7 bit. The ECC of each word is probably written to the same nonvolatile mem as the word itself. Therefore the same limitations apply. I.e. between erases, only additional bits can be set. The low-level interface to flash memory chips differs from those of other memory types such as DRAM, ROM, and EEPROM, which support bit-alterability (both zero to one and one to zero) and random access via externally accessible address buses. NOR memory has an external address bus for reading and programming. For …
