TABLE 6. SILICON ID CODE
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to re-
trieve data. The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The sys-
tem can read array data using the standard read tim-
ings, except that if it reads at an address within erase-
suspended sectors, the device outputs status data. Af-
ter completing a programming operation in the Erase
Suspend mode, the system may once again read array
data with the same exception. See erase Suspend/Erase
Resume Commands” for more infor-mation on this mode.
The system must issue the reset command to re-en-
able the device for reading array data if Q5 goes high, or
while in the autoselect mode. See the "Reset Command"
section, next.

RESET COMMAND
Writing the reset command to the device resets the
device to reading array data. Address bits are don't care
for this command.
The reset command may be written between the se-
quence cycles in an erase command sequence before
erasing begins. This resets the device to reading array
data. Once erasure begins, however, the device ignores
reset commands until the operation is complete.
The reset command may be written between the se-
quence cycles in a program command sequence be-fore
programming begins. This resets the device to reading
array data (also applies to programming in Erase Suspend
mode). Once programming begins, however, the device
ignores reset commands until the operation is complete.
The reset command may be written between the se-
quence cycles in an SILICON ID READ command
sequence. Once in the SILICON ID READ mode, the
reset command
data (also applies to SILICON ID READ during Erase
Suspend).
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to read-ing
array data (also applies during Erase Suspend).
