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.
8. SP: Standard power; LP: Low power.
