Figure 21 illustrates the Embedded Erase
TM
Algorithm using typical command strings and bus
operations.
Erase Suspend
The Erase Suspend command allows the user to interrupt a Sector Erase operation and then perform
data reads from or programs to a sector not being erased. This command is applicable ONLY during
the Sector Erase operation which includes the time-out period for sector erase. The Erase Suspend
command will be ignored if written during the Chip Erase operation or Embedded Program Algorithm.
Writing the Erase Suspend command during the Sector Erase time-out results in immediate
termination of the time-out period and suspension of the erase operation.
Writing the Erase Resume command resumes the erase operation. The addresses are DON’T CARES
when writing the Erase Suspend or Erase Resume command.
When the Erase Suspend command is written during the Sector Erase operation, the device will take a
maximum of 20
μ
s to suspend the erase operation. When the devices have entered the erase-
suspended mode, the RY/
BY
output pin and the DQ
7
bit will be at logic “1”, and DQ
6
will stop
toggling. The user must use the address of the erasing sector for reading DQ
6
and DQ
7
to determine if
the erase operation has been suspended. Further writes of the Erase Suspend command are ignored.
When the erase operation has been suspended, the devices default to the erase-suspend-read mode.
Reading data in this mode is the same as reading from the standard read mode except that the data
must be read from sectors that have not been erase-suspended. Successively reading from the
erase-suspended sector while the device is in the erase-suspend-read mode will cause DQ
2
to toggle.
(See the section on DQ
2
.)
After entering the erase-suspend-read mode, the user can program the device by writing the
appropriate command sequence for Program. This program mode is known as the
erase-suspend-program mode. Again, programming in this mode is the same as programming in the
regular Program mode except that the data must be programmed to sectors that are not
erase-suspended. Successively reading from the erase-suspended sector while the devices are in the
erase-suspend-program mode will cause DQ
2
to toggle. The end of the erase-suspended Program
operation is detected by the RY/
BY
output pin,
Data
polling of DQ
7
, or by the Toggle Bit I (DQ
6
)
which is the same as the regular Program operation. Note that DQ
7
must be read from the Program
address while DQ
6
can be read from any address.
To resume the operation of Sector Erase, the Resume command (30H) should be written. Any further
writes of the Resume command at this point will be ignored. Another Erase Suspend command can be
written after the chip has resumed erasing.
