The two extreme functionally equivalent possibilities of distributed or centralised crossbar function for realising a bank-based multiport memory are compared on the basis of required global signal and transistor numbers. With respect to both measures, the distributed crossbar function is found to be the better choice for practically relevant multiport-memory configurations.
