5K320 SATA OEM Specification

5.8ECC

The 10 bit symbol non interleaved ECC processor provides user data verification and correction capability. The first 6 symbol of ECC are 4 check symbols for user data and the 2 symbol system ECC. The other 34 symbols are Read Solomon ECC. Hardware logic corrects up to 16 symbols(20 bytes) errors on -the-fly.

2 symbol System ECC is generated when HDC receives user data from HOST, and can correct up to 1 symbol(10bit) errors on -the-fly when one transfers to HOST.
