The table below shows an example of how ECC is written to the redundant area in the
NAND Flash memory when using Reed-Solomon codes.
When using Hamming codes with SmartMedia™, the addresses of the redundant area
are specified by the physical format of SmartMedia™. For details, refer to the
SmartMedia™ Physical Format Specifications.
