The ECC is not performed on an individual byte basis.

Usually, 8 bytes are combined with one parity bit per byte. Giving a total of 72 bits.

Since only 7 parity bits are needed to correct single-bit errors and 8 are available the extra bit can be used to detect double bit errors, although not corrected.

The ECC is not performed on an individual byte basis.

Usually, 8 bytes are combined. If 8 bytes are combined then at least 7 syndrome bits are needed and 8 are available.
