Sector/Sector Block Protection and
Unprotection
(Note: For the following discussion, the term “sector”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Table
7).
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both pro-
gram and erase operations in previously protected
sectors. Sector protection/unprotection can be imple-
mented via two methods.
Table 7.
Am29DL642G Boot Sector/Sector Block
Addresses for Protection/Unprotection
The primary method requires V
ID
on the RESET# pin
only, and can be implemented either in-system or via
programming equipment. Figure 2 shows the algo-
rithms and Figure 23 shows the timing diagram. This
method uses standard microprocessor bus cycle tim-
ing. For sector unprotect, all unprotected sectors must
first be protected prior to the first sector unprotect
write cycle. Note that the sector unprotect algorithm
unprotects all sectors in parallel. All previously pro-
tected sectors must be individually re-protected. To
change data in protected sectors efficiently, the tem-
porary sector unprotect function is available. See
“Temporary Sector Unprotect”.
