| 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. | |
