We are currently using the S34ML08G101TFI000 with an stm32f767 and appears to work well.
We are using hardware ECC providing 1b per 512 bytes. For the above device we rd/wr in 512byte blocks generating an ECC for each block and storing the 4 ECC's in the spare memory.
My question; Is 1b per 512 adequate for the S34ML08G101TFI000.
We can move to 1b per 256 bytes but i am not sure this is necessary?
Yes 1bit ECC for 512 bytes is sufficient. There is no need to go for 1b per 256.
