Synchronous Address Status Controller: This active LOW input
interrupts any ongoing burst, causing a new external address to be
registered. A READ or WRITE is performed using the new address if
CE# is LOW. ADSC# is also used to place the chip into power-down
state when CE# is HIGH.
Mode: This input selects the burst sequence. A LOW on this pin
selects “linear burst.” NC or HIGH on this pin selects “interleaved
burst.” Do not alter input state while device is operating.
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.
versions, Byte “a” is associated with DQa pins; Byte “b” is
associated with DQb pins; Byte “c” is associated with DQc pins;
Byte “d” is associated with DQd pins. Input data must meet setup
and hold times around the rising edge of CLK.
No Connect/Parity Data I/Os: On the x32 version, these pins are No
Connect (NC). On the x18 version, Byte “a” parity is DQPa; Byte “b”
parity is DQPb. On the x36 version, Byte “a” parity is DQPa; Byte
“b” parity is DQPb; Byte “c” parity is DQPc; Byte “d” parity is DQPd.

Operating Conditions for range.
Do Not Use: These signals may either be unconnected or wired to
GND to improve package heat dissipation.
No Connect: These signals are not internally connected and may be
connected to ground to improve package heat dissipation.
No Connect: This pin is reserved for address expansion.
