5.3 Copy-Back Program
Copy-Back program with Read for Copy-Back is configured to quickly and efficiently rewrite data stored in one page. The benefit is especially obvious
when a portion of a block is updated and the rest of the block also needs to be copied to the newly assigned free block. Copy-Back operation is a sequen-
tial execution of Read for Copy-Back and of copy-back program with the destination page address. A read operation with "35h" command and the
address of the source page moves the whole 2,112-byte data into the internal data buffer. A bit error is checked by sequential reading the data output. In
the case where there is no bit error, the data do not need to be reloaded. Therefore Copy-Back program operation is initiated by issuing Page-Copy Data-
Input command (85h) with destination page address. Actual programming operation begins after Program Confirm command (10h) is issued. Once the
program process starts, the Read Status Register command (70h) may be entered to read the status register. The system controller can detect the com-
pletion of a program cycle by monitoring the R/B output, or the Status bit(I/O 6) of the Status Register. When the Copy-Back Program is complete, the
Write Status Bit(I/O 0) may be checked(Figure 10). The command register remains in Read Status command mode until another valid command is written
to the command register.
During copy-back program, data modification is possible using random data input command (85h) as shown in Figure 11.
NOTE :
Copy-Back Program operation is allowed only within the same memory plane.
