Data Sheet
Software Data Protection (SDP)
These devices provide the JEDEC standard Software Data
Protection scheme for all data alteration operations, i.e.,
Program and Erase. Any Program operation requires the
inclusion of the three-byte sequence. The three-byte load
sequence is used to initiate the Program operation, provid-
ing optimal protection from inadvertent Write operations,
e.g., during the system power-up or power-down. Any
Erase operation requires the inclusion of the six-byte
sequence. The devices are shipped with the Software Data
Protection permanently enabled. See Table 6 for the spe-
cific software command codes. During SDP command
sequence, invalid commands will abort the device to Read
mode within T
V
sequence.
Common Flash Memory Interface (CFI)
These devices also contain the CFI information to
describe the characteristics of the devices. In order to
enter the CFI Query mode, the system must write the
three-byte sequence, same as the Software ID Entry com-
mand with 98H (CFI Query command) to address 555H in
the last byte sequence. See Figure 17 for CFI Entry and
Read timing diagram. Once the device enters the CFI
Query mode, the system can read CFI data at the
addresses given in Tables 7 through 9. The system must
write the CFI Exit command to return to Read mode from
the CFI Query mode.

Security ID
The GLS36VF160xE devices offer a 256-bit Security ID
space. The Secure ID space is divided into two 128-bit seg-
ments—one factory programmed segment and one user
programmed segment. The first segment is programmed
and locked at Greenliant with a unique, 128-bit number.
The user segment is left un-programmed for the customer
to program as desired. To program the user segment of the
Security ID, the user must use the Security ID Program
command. End-of-Write status is checked by reading the
toggle bits. Data# Polling is not used for Security ID End-of-
Write detection. Once programming is complete, the Sec
ID should be locked using the User Sec ID Program Lock-
Out. This disables any future corruption of this space. Note
that regardless of whether or not the Sec ID is locked, nei-
ther Sec ID segment can be erased. The Secure ID space
can be queried by executing a three-byte command
sequence with Query Sec ID command (88H) at address
555H in the last byte sequence. See Figure 19 for timing
diagram. To exit this mode, the Exit Sec ID command
should be executed. Refer to Table 6 for more details.
