Read Operations
4.1
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
IL
to V
IH
), all partitions default to asynchronous read-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
PP
.
4.2
Read Device ID
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
Table 7
retrieve
ID information. Issuing a Read 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.
