Modes of Operation
Read Mode
The flash memory has four read modes (read array, read identifier, read status, and CFI query), and
two write modes (program and erase). Three additional modes (erase suspend to program, erase
suspend to read, and program suspend to read) are available only during suspended operations.

Read Array
When RP# transitions from V
respond to the read-control inputs (CE#, address inputs, and OE#) without any additional CUI
commands.
When the device is in read array mode, four control signals control data output.
In addition, the address of the desired location must be applied to the address pins. If the device is
not in read-array mode, as would be the case after a Program or Erase operation, the Read Array
command (0xFF) must be issued to the CUI before array reads can occur.
Read Identifier
The read-identifier mode outputs three types of information: the manufacturer/device identifier, the
block locking status, and the protection register. The device is switched to this mode by issuing the
Read Identifier command (0x90). Once in this mode, read cycles from addresses shown in
retrieve the specified information. To return to read-array mode, issue the Read Array command
(0xFF).
