DESCRIPTION
Synchronous Address Inputs: These inputs are registered and must
meet the setup and hold times around the rising edge of CLK.

Input
Synchronous Byte Write Enables: These active LOW inputs allow
individual bytes to be written and must meet the setup and hold
times around the rising edge of CLK. A byte write enable is LOW
for a WRITE cycle and HIGH for a READ cycle. For the x18 version,
BWa# controls DQa’s and DQPa; BWb# controls DQb’s and DQPb.
For the x32 and x36 versions, BWa# controls DQa’s and DQPa; BWb#
controls DQb’s and DQPb; BWc# controls DQc’s and DQPc; BWd#
controls DQd’s and DQPd. Parity is only available on the x18 and x36
versions.
Synchronous Clock Enable: This active LOW input permits CLK to
propogate throughout the device. When CKE# is HIGH, the device
ignores the CLK input and effectively internally extends the
previous CLK cycle. This input must meet the setup and hold times
around the rising edge of CLK.
Read/Write: This input determines the cycle type when ADV/LD# is
LOW and is the only means for determining READs and WRITEs.
READ cycles may not be converted into WRITEs (and vice versa)
other than by loading a new address. A LOW on this pin permits
BYTE WRITE operations to meet the setup and hold times around
the rising edge of CLK. Full bus-width WRITEs occur if all byte write
enables are LOW.
Clock: This signal registers the address, data, chip enable, byte write
enables, and burst control inputs on its rising edge. All synchronous
inputs must meet setup and hold times around the clock’s rising
edge.
Synchronous Chip Enable: This active LOW input is used to enable
the device and conditions the internal use of ADSP#. CE# is sampled
only when a new external address is loaded.
Synchronous Chip Enable: This active LOW input is used to enable
the device and is sampled only when a new external address is
loaded.
Snooze Enable: This active HIGH, asynchronous input causes the
device to enter a low-power standby mode in which all data in the
memory array is retained. When ZZ is active, all other inputs are
ignored.
Synchronous Chip Enable: This active HIGH input is used to enable
the device and is sampled only when a new external address is
loaded.
Output Enable: This
active LOW, asynchronous input enables the
data I/O output drivers.
