Copy back program
The copy back program operation is used to copy the data stored in one page and
reprogram it in another page.
The copy back program operation does not require external memory and so the operation is
faster and more efficient because the reading and loading cycles are not required. The
operation is particularly useful when a portion of a block is updated and the rest of the block
needs to be copied to the newly assigned block.
If the copy back program operation fails an error is signalled in the status register. However
as the standard external ECC cannot be used with the copy back operation bit error due to
charge loss cannot be detected. For this reason it is recommended to limit the number of
copy back operations on the same data and or to improve the performance of the ECC.
The copy back program operation requires two steps:
1.
2.
3.
After a copy back program operation, a partial-page program is not allowed in the target
page until the block has been erased.

The source page must be read using the Read A command (one bus write cycle to
setup the command and then 4 bus write cycles to input the source page address).
This operation copies all 264 words/ 528 bytes from the page into the page buffer
When the device returns to the ready state (Ready/Busy High), the second bus write
cycle of the command is given with the 4 bus cycles to input the target page address.
