Sector Erase and Program Suspend Command
Automatic sector erase operations begin on the rising edge of the WE# or CE#
pulse of the last sector erase command issued, and once the 80 µs time-out win-
dow expires. The status of the sector erase operation is determined three ways:
Further status of device activity during the sector erase operation is determined
using toggle bit DQ2 (refer to
When the Embedded Erase algorithm is complete, the device returns to reading
array data, and addresses are no longer latched. Note that an address change is
required to begin read valid array data.

Figure 21, on page 78
The Sector Erase and Program Suspend command allows the user to interrupt a
Sector Erase or Program operation and perform data read or programs in a sector
that is not being erased or to the sector where a programming operation was ini-
tiated. This command is applicable only during the Sector Erase and
Programming operation, which includes the time-out period for Sector Erase.
