Figure 6. 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. This command is valid only during the sector erase
operation, including the 50 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 Program algorithm.
When the Erase Suspend command is written during the sector erase operation, the device requires a typical of
5 s (maximum of 20 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.
After the erase operation has been suspended, the device enters the erase-suspend-read mode. The system can
read data from or program data to any sector not selected for erasure. (The device “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 device returns to the erase-suspend-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.
In the erase-suspend-read mode, the system can also issue the autoselect command sequence. Refer to the “Au-
toselect Mode” section on page 79 and “Autoselect Command Sequence” section on page 104 sections for details.
