FLASH DEVICE BUS OPERATIONS
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

pins DQ14–DQ8 are tri-stated, and the DQ15 pin is
used as an input for the LSB (A-1) address function.
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#
