Anyone here knowledgeable about eMMC memory?
I have a high reliability application where there is concern about
memory corruption. What would happen if I changed the ECC field in the
eMMC's Card Specific Data (CSD) register from the default no ECC to the optional BCH(542,512) encoding? Would I still be able to write/read new values to the eMMC normally with the eMMC internally protecting the
contents with BCH ECC at the cost of reduced memory capacity, or would a special driver on the host be needed to encode/decode ECC reads/writes?
I've asked around and haven't found a definitive answer so far. Let me
know if you can help ... Buzz
