Erase operation, DQ5 outputs a 1. This indicates that the operation has not been completed within the allotted time.
Any attempt to program a 1 into a cell containing a 0 will fail (see Auto-Program Mode). In this case, DQ5 outputs a 1. In this
case, DQ5 doesn’t indicate defective device but mistaken usage.
After an Auto-Program or auto-erase operation ends normally, the device outputs actual cell array data. Therefor only with the
data of DQ5 can’t specify whether cell array data or hardware sequence flag. The hosts shuold check the state of device

outputs a 0 for the duration of the Block Erase Hold Time and a 1 when the Block Erase operation starts. Additional Block
Erase commands can only be accepted during the Block Erase Hold Time. Each Block Erase command input within the hold
time resets the timer, allowing additional blocks to be marked for erasing. DQ3 outputs a 1 if the Program or Erase operation
fails.

If data is read continuously from the selected block during an Auto Block Erase, the DQ2 output will toggle. Now 1 will be
output from non-selected blocks; thus, the selected block can be ascertained. If data is read continuously from the block
selected for Auto Block Erase while the device is in Erase Suspend Mode, the DQ2 output will toggle. Because the DQ6 output
is not toggling, it can be determined that the device is in Erase Suspend Mode. If data is read from the address to which data is
being written during Erase Suspend in Programming Mode, DQ2 will output a 1.
