ERASE SUSPEND/ERASE RESUME
COMMAND SEQUENCE
The Erase Suspend command 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
μ
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. Writing the Erase
Suspend command during the Sector Erase time-out immediately
terminates the time-out period and suspends the erase operation.
Addresses are “don't cares” when writing the Erase Suspend
command.
When the Erase Suspend command is written during a sector
erase operation, the device requires a maximum of 20
μ
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 system can
read array data from or program data to any sector not selected for
erasure. (The device “erase suspends” all sectors selected for
erasure.) Normal read and write timings and command definitions
apply. Reading at any address within erase-suspended sectors
produces status data on FD
7-0
. The system can use FD
7
, or FD
6
, and
FD
2
together, to determine if a sector is actively erasing or is erase
suspended. See "Write Operation Status" for information on these
status bits.
After an erase-suspended program operation is complete, the
system can once again read array data within non-suspended
sectors. The system can determine the status of the program
operation using the FD
7
or FD
6
status bits, just as in the standard
program operation. See the “Write Operation Status” for more
information.
The system may also write the autoselect command sequence
when the device is in the Erase Suspend mode. The device allows
reading autoselect codes even at addresses within erasing sectors,
since the codes are not stored in the memory array. When the
device exits the autoselect mode, the device reverts to the Erase
Suspend mode, and is ready for another valid operation.
The system must write the Erase Resume command (address bits
are “don't care”) to exit the erase suspend mode and continue the
sector erase operation. Further writes of the Resume command
are ignored. Another Erase Suspend command can be written
after the device has resumed erasing.
