10.2 Customer Secured Silicon Sector
The Customer Secured Silicon Sector is typically shipped unprotected (DQ6 set to
0
), allowing
customers to utilize that sector in any manner they choose. If the security feature is not required,
the Customer Secured Silicon Sector can be treated as an additional Flash memory space.
Please note the following:
Once the Customer Secured Silicon Sector area is protected, the Customer Indicator Bit is
permanently set to
1
.
The Customer Secured Silicon Sector can be read any number of times, but can be pro-
grammed and locked only once. The Customer Secured Silicon Sector lock must be used with
caution as once locked, there is no procedure available for unlocking the Customer Secured
Silicon Sector area and none of the bits in the Customer Secured Silicon Sector memory space
can be modified in any way.
The accelerated programming (ACC) and unlock bypass functions are
not
available when pro-
gramming the Customer Secured Silicon Sector, but are available when reading in Banks B
through D.
Once the Customer Secured Silicon Sector is locked and verified, the system must write the
Exit Secured Silicon Sector Region command sequence which return the device to the mem-
ory array at sector 0.
10.3 Secured Silicon Sector Entry and Exit Command Sequences
The system can access the Secured Silicon Sector region by issuing the three-cycle Enter Secured
Silicon Sector command sequence. The device continues to access the Secured Silicon Sector re-
gion until the system issues the four-cycle Exit Secured Silicon Sector command sequence.
See the Command Definition Tables
Table 12.1, Memory Array Commands
.
Table 12.2, Sector Protection Commands
for address and data requirements for both command
sequences.
The Secured Silicon Sector Entry Command allows the following commands to be executed
Read customer and factory Secured Silicon areas
Program the customer Secured Silicon Sector
After the system has written the Enter Secured Silicon Sector command sequence, it may read
the Secured Silicon Sector by using the addresses normally occupied by sector SA0 within the
memory array. This mode of operation continues until the system issues the Exit Secured Silicon
Sector command sequence, or until power is removed from the device.
The following are C functions and source code examples of using the Secured Silicon Sector
Entry, Program, and exit commands. Refer to the
Spansion Low Level Driver User Guide
(available soon on
www.amd.com
and
www.fujitsu.com
) for general information on Spansion
Flash memory software development guidelines.
