CLK
Input
Positive
The system clock input. All of the SDRAM inputs are sampled on the rising edge of the clock.
Edge
CKE
Input
Active
High
CKE activates the CLK signal when high and deactivates the CLK signal when low. By deactivating the clock, CKE low initiates the Power Down mode, Suspend mode, or the Self Refresh
mode.
CS,
CS0, CS1
Input
Active
Low
CS (CS0, CS1 for stacked devices) enables the command decoder when low and disables the
command decoder when high. When the command decoder is disabled, new commands are
ignored but previous operations continue.
RAS, CAS, WE
Input
Active
Low
When sampled at the positive rising edge of the clock, CAS, RAS, and WE define the operation
to be executed by the SDRAM.
BS1, BS0
Input
—
Selects which bank is to be active.
A0 - A11
Input
—
During a Bank Activate command cycle, A0-A11 defines the row address when sampled at the
rising clock edge.
During a Read or Write command cycle, A0-A9 defines the column address when sampled at
the rising clock edge.
A10 is used to invoke auto-precharge operation at the end of the burst read or write cycle. If A10
is high, auto-precharge is selected and BS0, BS1 defines the bank to be precharged. If A10 is
low, autoprecharge is disabled.
During a Precharge command cycle, A10 is used in conjunction with BS0, BS1 to control which
bank(s) to precharge. If A10 is high, all banks will be precharged regardless of the state of BS. If
A10 is low, then BS0 and BS1 are used to define which bank to precharge.
DQ0-DQ3
InputOutput
—
Data Input/Output pins operate in the same manner as on conventional DRAMs.
DQM
Input
Active
High
VDD, VSS
Supply
VDDQ, VSSQ
Supply
The Data Input/Output mask places the DQ buffers in a high impedance state when sampled
high. In Read mode, DQM has a latency of two clock cycles and controls the output buffers like
an output enable. DQM low turns the output buffers on and DQM high turns them off. In Write
mode, DQM has a latency of zero and operates as a word mask by allowing input data to be
written if it is low but blocks the write operation if DQM is high.
Power and ground for the input buffers and the core logic.
—
Isolated power supply and ground for the output buffers to provide improved noise immunity.

1. All of the SDRAM operations are defined by states of CS, WE, RAS, CAS, and DQM at the positive rising edge of the clock.Operation of both decks of a stacked device at the same time is allowed, depending on the operation being performed on the other
deck. Refer to the Current State Truth Table.
2. Bank Select (BS0, BS1): BS0, BS1 = 0,0 selects bank 0; BS0, BS1 = 0,1 selects bank 1; BS0, BS1 = 1,0 selects bank 2; BS0, BS1
= 1,1 selects bank 3.
3. During a Burst Write cycle there is a zero clock delay, for a Burst Read cycle the delay is equal to the CAS latency.
4. During normal access mode, CKE is held high and CLK is enabled. When it is low, it freezes the internal clock and extends data
Read and Write operations. One clock delay is required for mode entry and exit.
5. The DQM has two functions for the data DQ Read and Write operations. During a Read cycle, when DQM goes high at a clock timing the data outputs are disabled and become high impedance after a two clock delay. DQM also provides a data mask function for
Write cycles. When it activates, the Write operation at the clock is prohibited (zero clock latency).
6. All banks must be precharged before entering the Power Down Mode.(If this command is issued during a burst operation, the
device state will be Clock Suspend Mode.)The Power Down Mode does not perform any refresh operations, therefore the device
can’t remain in this mode longer than the Refresh period (tREF) of the device. One clock delay is required for mode entry and exit.
7. A No Operation or Device Deselect command is required on the next clock edge following CKE going high.
8. Device state is full page burst operation. Use of this command to terminate other burst length operations is illegal.

1. Currents given are valid for a single device. The total current for a stacked device depends on the operation being performed on the
other deck.
2. These parameters depend on the cycle rate and are measured with the cycle determined by the minimum value of tCK and tRC.
Input signals are changed up to three times during tRC(min).
3. The specified values are obtained with the output open.
4. Input signals are changed once during tCK(min).
5. Input signals are changed once during three clock cycles.
6. Active Standby Current will be higher if Clock Suspend is entered during a burst read cycle (add 1mA per DQ).
7. Input signals are stable.

1. See full specification (19L3264) for power-up requirements.
2. The Transition time is measured between VIH and VIL (or between VIL and VIH).
3. In addition to meeting the transition rate specification, the clock and CKE must transit between VIH and VIL (or between VIL and VIH)
in a monotonic manner.
4. AC timing tests have VIL = 0.8 V and VIH = 2.0 V with the timing referenced to the 1.40V crossover point
5. AC measurements assume tT = 1.2ns.
