- This adds an extra check when data is written to the flash. The
- OneNAND flash device internally checks only bits transitioning
- from 1 to 0. There is a rare possibility that even though the
- device thinks the write was successful, a bit could have been
- flipped accidentally due to device wear or something else.

- One Block of the NAND Flash Array memory is reserved as
- a One-Time Programmable Block memory area.
- Also, 1st Block of NAND Flash Array can be used as OTP.
- The OTP block can be read, programmed and locked using the same
- operations as any other NAND Flash Array memory block.
- OTP block cannot be erased.
- OTP block is fully-guaranteed to be a valid block.
