10. Secured Silicon Sector Flash Memory Region
The Secured Silicon Sector provides an extra Flash memory region that enables permanent part identification
through an Electronic Serial Number (ESN). The Secured Silicon Sector is a 256-byte flash memory area that
is either programmable at the customer, or by Spansion at the request of the customer. See
Table 10.1
for the
Secured Silicon Sector address ranges.
All Secured Silicon reads outside of the 256-byte address range return invalid data.
The device allows Simultaneous Read/Write operation while the Secured Silicon Sector is enabled. However,
several restrictions are associated with Simultaneous Read/Write operation and device operation when the
Secured Silicon Sector is enabled:
1. The Secured Silicon Sector is not available for reading while the Password Unlock, any PPB
program/erase operation, or Password programming are in progress. Reading to any location in
the small bank will return the status of these operations until these operations have completed
execution.
2. Programming the DYB associated with the overlaid boot-block sector results in the DYB NOT being
updated. This occurs only when the Secured Silicon sector is not enabled.
3. Reading the DYB associated with the overlaid boot-block sector when the PPB Lock/DYB Verify
command is issued, causes the read command to return invalid data. This function occurs only
when the Secured Silicon Sector is not enabled.
4. All commands are available for execution when the Secured Silicon Sector is enabled, except the
following:
a. Any Unlock Bypass command
b. CFI
c. Accelerated Program
d. Program and Sector Erase Suspend
e. Program and Sector Erase Resume
Issuing the above commands while the Secured Silicon Sector is enabled results in the command being
ignored.
5. It is valid to execute the Sector Erase command on any sector other than the Secured Silicon
Sector when the Secured Silicon Sector is enabled. However, it is not possible to erase the
Secured Silicon Sector using the Sector Erase Command, as it is a one-time programmable (OTP)
area that can not be erased.
6. Executing the Chip Erase command is permitted when the Secured Silicon Sector is enabled. The
Chip Erase command erases all sectors in the memory array, except for sector 0 in top-boot block
configuration, or sector 45 in bottom-boot block configuration. The Secured Silicon Sector is a one-
time programmable memory area that cannot be erased.
7. Executing the Secured Silicon Sector Entry command during program or erase suspend mode is
allowed. The Sector Erase/Program Resume command is disabled when the Secured Silicon
sector is enabled; the user cannot resume programming of the memory array until the Exit Secured
Silicon Sector command is written.
8. Address range 00040h–007FFh for the top bootblock, and FF00h–FFF7Fh return invalid data
when addressed with the Secured Silicon sector enabled.
9. The Secured Silicon Sector Entry command is allowed when the device is in either program or
erase suspend modes. If the Secured Silicon sector is enabled, the program or erase suspend
command is ignored. This prevents resuming either programming or erasure on the Secured
Table 10.1
