All RAMs have ECC protection with a 32-bit granularity. This means that every 32 bits has 7 bits of ECC. ECC for write data is generated in the CPU and written to memory directly. The read-modify-write operation is performed within the MEMSS memory controller for accesses that are less than 32 bits, and the ECC is generated locally for these write accesses.
