Table 3. 4K-bit Secured OTP Definition

II. Additional 4K-bit secured OTP for unique identifier: to provide 4K-bit One-Time Program area for setting de-

vice unique serial number - Which may be set by factory or system maker. Please refer to "Table 3. 4K-bit Se-

cured OTP Definition".

- Security register bit 0 indicates whether the chip is locked by factory or not.

- To program the 4K-bit secured OTP by entering 4K-bit secured OTP mode (with ENSO command), and going

through normal program procedure, and then exiting 4K-bit secured OTP mode by writing EXSO command.

- Customer may lock-down the customer lockable secured OTP by writing WRSCUR(write security register)

command to set customer lock-down bit1 as "1". Please refer to "Table 9. Security Register Definition" for secu-

rity register bit definition and "Table 3. 4K-bit Secured OTP Definition" for address range definition.

Note:

Once lock-down whatever by factory or customer, it cannot be changed any more. While in 4K-bit Secured OTP

mode, array access is not allowed.
