execute the command. The contents of the register serve as inputs to the internal state machine. The state
machine outputs dictate the function of the device.
control levels they require, and the resulting output. The following subsections describe each of these
operations in further detail.
The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the
BYTE# pin is set at logic 1, the device is in word configuration, DQ0–DQ15 are active and controlled by CE#
and OE#.
If the BYTE# pin is set at logic 0, the device is in byte configuration, and only data I/O pins DQ0–DQ7 are
active and controlled by CE# and OE#. The data I/O pins DQ8–DQ14 are tri-stated, and the DQ15 pin is used
as an input for the LSB (A-1) address function.
To read array data from the outputs, the system must drive the CE# and OE# pins to V
control and selects the device. OE# is the output control and gates array data to the output pins. WE# should
remain at V
The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory content occurs during the power transition. No command is
necessary in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses
on the device address inputs produce valid data on the device data outputs. The device remains enabled for
read access until the command register contents are altered.
See
timing specifications and the timing diagram. Refer to the DC Characteristics table for the active current
specification on reading array data.
