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 com-
mand is valid only during the sector erase operation, including the 80 μs 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 maximum of 35 μs to suspend the erase operation. How-
ever, 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-sus-
pend-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 sta-
tus 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
section for information on these status
bits.
After an erase-suspended program operation is complete, the bank returns to the
erase-suspend-read mode. The system can determine the status of the program
