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.
