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.

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 accidentaly due to device wear or something else.
