Read Identifier Codes Operation
automatically match the device with its proper
algorithms. The block status codes identify locked
or unlocked block setting and erase completed or
erase uncompleted condition.
The read identifier codes operation outputs the
manufacture code, device code, block status codes
for each block (see
Fig. 2).
Using the manufacture
and device codes, the system CPU can

Query Operation
3.7
Write
The query operation outputs the query structure.
Query database is stored in the 48-byte ROM per
bank. Query structure allows system software to
gain critical information for controlling the flash
component. Query structures are always presented
on the lowest-order data output (DQ
0
-DQ
7
) only.
Writing commands to the CUI enable reading of
device data and identifier codes. They also control
inspection and clearing of the status register. When

CC1/2

, the CUI
additionally controls block erase, bank erase, (multi)
word/byte write and block lock-bit configuration.
