READING ARRAY DATA

The device is automatically set to reading array data

after device power-up. No commands are required to

retrieve 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. After

completing a programming operation in the Erase

Suspend mode, the system may once again read array

data with the same exception. See rase 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 must be written to return to reading array

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).
