RAS Features
shows the ECC H-Matrix used by the memory controller. The table shows the
supported single-error syndromes that are detectable during a read. The all zero
syndrome indicates that no error was detected. All of the valid single error syndromes
contain a odd number of 1s asserted. The 72 syndromes for data and ECC bits are
treated as single-bit (correctable) errors. All other non-zero syndromes are treated as
multiple-bit (uncorrectable) errors.
