Command
(block)
After erasing the block in error, execute write
operation one more time. If the same error still
occurs, the block in error cannot be used.
Execute the read lock bit status command (71
see if the block is locked. After removing lock,
execute write operation in the same way. If the
error still occurs, the page in error cannot be used.
Execute the clear status register command (50
to clear the status register. Try performing the
operation one more time after confirming that the
command is entered correctly.
Should a block erase error occur, the block in error
