eMMC CSD Register ECC field

Show all headers | View raw

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
