*Note: 1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions above those indicated in the operating sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. VDDQ must not exceed VDD during normal operation.

Notes: 1. Minimum cycle. IOUT=0mA.
2. |IOH|=(VDDQ/2)/(RQ/5)±15% for 175Ω ≤ RQ ≤ 350Ω.
3. |IOL|=(VDDQ/2)/(RQ/5)±15% for 175Ω ≤ RQ ≤ 350Ω.
4. Minimum Impedance Mode when ZQ pin is connected to VDDQ.
5. Operating current is calculated with 50% read cycles and 50% write cycles.
6. Standby Current is only after all pending read and write burst operations are completed.
7. Programmable Impedance Mode.
8. These are DC test criteria. DC design criteria is VREF±50mV. The AC VIH/VIL levels are defined separately for measuring
timing parameters.
9. VIL (Min) DC=-0.3V, VIL (Min) AC=-1.5V(pulse width ≤ 3ns).
10. VIH (Max)DC=VDDQ+0.3, VIH (Max)AC=VDDQ+0.85V(pulse width ≤ 3ns).
