Temporary Sector Group Unprotect
February 7, 2007 S29GL-M_00_B8
This feature allows temporary unprotection of previously protected sector groups to change data
in-system. The Sector Group Unprotect mode is activated by setting the RESET# pin to
ing this mode, formerly protected sector groups can be programmed or erased by selecting the
sector group addresses. Once V
sector groups are protected again. For this feature,
shows the timing diagrams.
Notes:

2.
All protected sector groups unprotected (If WP# = V
remains protected for uniform sector devices, the top or bottom two address sectors remains
protected for boot sector devices).
All previously protected sector groups are protected once again.
