| 19 | help | |
| 20 | This adds an extra check when data is written to the flash. The | |
| 21 | OneNAND flash device internally checks only bits transitioning | |
| 22 | from 1 to 0. There is a rare possibility that even though the | |
| 23 | device thinks the write was successful, a bit could have been | |
| 09509603 | 24 | flipped accidentally due to device wear or something else. |

| 36 | One Block of the NAND Flash Array memory is reserved as | |
| 37 | a One-Time Programmable Block memory area. | |
| 38 | Also, 1st Block of NAND Flash Array can be used as OTP. | |
| 39 | ||
| 40 | The OTP block can be read, programmed and locked using the same | |
| 41 | operations as any other NAND Flash Array memory block. | |
| 42 | OTP block cannot be erased. | |
| 43 | ||
| 44 | OTP block is fully-guaranteed to be a valid block. | |
