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.
