4. Minimum Impedance Mode when ZQ pin is connected to V
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 V
