2. See the section on DQ3 for information on the sector erase timer.
Figure 10 Erase Operation
Erase Suspend/Erase Resume Commands
The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and
then read data from, or program data to, any sector not selected for erasure. The bank address
is required when writing this command. This command is valid only during the sector erase op-
eration, including the 80 s time-out period during the sector erase command sequence. The
Erase Suspend command is ignored if written during the chip erase operation or Embedded Pro-
gram algorithm.
When the Erase Suspend command is written during the sector erase operation, the device re-
quires a maximum of 35 s to suspend the erase operation. However, when the Erase Suspend
command is written during the sector erase time-out, the device immediately terminates the
time-out period and suspends the erase operation. Addresses are “don’t-cares” when writing the
Erase suspend command.
After the erase operation has been suspended, the bank enters the erase-suspend-read mode.
The system can read data from or program data to any sector not selected for erasure. (The de-
vice “erase suspends” all sectors selected for erasure.) Reading at any address within
erase-suspended sectors produces status information on DQ7–DQ0. The system can use DQ7,
or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended.
Refer to the Write Operation Status section for information on these status bits.
After an erase-suspended program operation is complete, the bank returns to the erase-sus-
pend-read mode. The system can determine the status of the program operation using the DQ7
or DQ6 status bits, just as in the standard Word Program operation. Refer to the Write Operation
Status section for more information.
