Notes:
1. Other operations except for those indicated in this column are inhibited.
2. Do not apply CE#f = V
3. Don’t care or open LB#s or UB#s.

Word/Byte Configuration
The CIOf pin controls whether the device data I/O pins
operate in the byte or word configuration. If the CIOf
pin is set at logic ‘1’, the device is in word configura-
tion, DQ15–DQ0 are active and controlled by CE#f
and OE#.
If the CIOf pin is set at logic ‘0’, the device is in byte
configuration, and only data I/O pins DQ7–DQ0 are
active and controlled by CE#f and OE#. The data I/O

Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE#f and OE# pins to V
control and selects the device. OE# is the output con-
trol and gates array data to the output pins. WE#
should remain at V
whether the device outputs array data in words or
bytes.
