Effect of ZQ pin on address lines

Version 1
    Question: Does using the ZQ pin affect the address lines?



    No, using the ZQ pin does not affect the address lines. The ZQ pin is used to control the drive strength of the output drivers. By using the ZQ pin, the output impedance of the device can be varied from 35 Ohms to 70 Ohms. This can be accomplished by connecting a resistor whose value is five times the required impedance at the ZQ pin.
