READ FOR COPY-BACK WITH DATA OUTPUT TIMING GUIDE
Copy-Back operation is a sequence 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 source page moves the
whole 4328byte data into the internal data buffer. Bit errors are checked by sequential reading the data. In the
case where there is no bit error, the data don’t need to be reloaded. Therefore Copy-Back program operation is
initiated by issuing Page-Copy Data-Input command (85h) with destination page address. Acutual programming
operation begins after Program Confirm command (10h) is issued. Once the program process starts, the Read
Status Register command (70h) may be enterd to read the status register. The system contoller can detect the
completion of a program cycle by monitoring the RY /BY output, or the Status Bit (I/O7) of the Status Register.
When the Copy-Back Program is complete, the Write Status Bit (I/O1) may be checked. 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 randam data input command (85h) as shown
below.
