Copy Back Program
The Copy Back Program operation is used to copy
the data stored in one page and reprogram it in an-
other page.
The Copy Back Program operation does not re-
quire 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 up-
dated 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 recom-
mended to limit the number of Copy Back opera-
tions on the same data and or to improve the
performance of the ECC.
The Copy Back Program operation requires three
steps:
1. The source page must be read using the Read
