Scrubbing
Once an error is detected within the memory array, the SMCU must correct the error (if
possible) while delivering the data to the initiator. Correcting the memory location is referred
to as “scrubbing the array.” The SMCU relies on software to scrub any errors.
Syndrome
A syndrome is a value which indicates an error in the data read from the memory array. The
SMCU computes the syndrome with every memory read. Decoding the syndrome indicates:
the bit in error for a single-bit error, or a multi-bit error.
Table 346
defines the syndrome
decoding.
