1. Copy-Back Program operation is allowed only within the same memory plane.
2. On the same plane, It’s prohibited to operate copy-back program from an odd address page(source page) to an even
address page(target page) or from an even address page(source page) to an odd address page(target page).
Therefore, the copy-back program is permitted just between odd address pages or even address pages.
3. EDC status Bits are not available during copy back for some bits or bytes modified by Random Data Input operation.
In case of the 528 byte plane unit modification, EDC status bits are available.
