output on valid CLK edges following a minimum delay. However, for a synchronous non-
array read, the same word of data will be output on successive clock edges until the
burst length requirements are satisfied. See During synchronous read operations, WAIT
indicates invalid data when asserted, and valid data when deasserted with respect to a
valid clock edge. See
Read Array
The Read Array command places (or resets) the partition in read-array mode and is
used to read data from the flash memory array. Upon initial device power-up, or after
reset (RST# transitions from V
array mode. To read array data from the flash device, first write the Read Array
command (FFh) to the CUI and specify the desired word address. Then read from that
address. If a partition is already in read-array mode, issuing the Read Array command
is not required to read from that partition.
If the Read Array command is written to a partition that is erasing or programming, the
device presents invalid data on the bus until the program or erase operation completes.
After the program or erase finishes in that partition, valid array data can then be read.
If an Erase Suspend or Program Suspend command suspends the WSM, a subsequent
Read Array command places the addressed partition in read-array mode. The Read
Array command functions independently of V
Read Identifier
The Read Identifier mode outputs the manufacturer/device identifier, block lock status,
protection register codes, and Configuration Register data. The identifier information is
contained within a separate memory space on the device and can be accessed along
the 4-Mbit partition address range supplied by the Read Identifier command (90h)
address. Reads from addresses in
Identifier command to a partition that is programming or erasing places that partition’s
outputs in read ID mode while the partition continues to program or erase in the
background.
