Memory IC FAQ

How does the QDR-II architecture handle data contention?

It uses separate read and write ports to completely eliminate the need for data bus turnaround, thereby avoiding data contention.

What is the function of the ZQ pin?

The ZQ pin is used for impedance matching. An external resistor connects it to ground to tune the output driver impedance to the system data bus.
