The copy-back program is configured to quickly and efficiently rewrite data stored in one page within the plane to another page within
the same plane without utilizing an external memory. Since the time-consuming sequently-reading and its re-loading cycles are
removed, the system performance is improved. The benefit is especially obvious when a portion of a block is updated and the rest of
the block also need to be copied to the newly assigned free block. The operation for performing a copy-back program is a sequential
execution of page-read without burst-reading cycle and copying-program with the address of destination page. A normal read opera-
tion with "00h" command and the address of the source page moves the whole 528byte data into the internal page registers. As soon
as the device returns to Ready state, Page-Copy Data-input command (8Ah) with the address cycles of destination page followed
may be written. The Program Confirm command (10h) is required to actually begin the programming operation. Copy-Back Program
operation is allowed only within the same memory plane. Once the Copy-Back Program is finished, any additional partial page pro-
gramming into the copied pages is prohibited before erase. A14 and A15 must be the same between source and target page.
Figure19 shows the command sequence for single plane operation.
"When there is a program-failure at Copy-Back operation,
error is reported by pass/fail status. But, if Copy-Back operations are accumulated over time, bit error due to charge loss is
not checked by external error detection/correction scheme. For this reason, two bit error correction is recommended for
the use of Copy-Back operation."
