1. A method for communication between an IC (integrated circuit) and an external RAM (random access memory), where the external RAM has at least one memory bank and communication between the IC and the external RAM is performed via two or more channels, at least one of the channels is one of a dedicated input and output channel, where data exchange between the IC and the external RAM necessitates at least two memory bank commands, the method comprising: receiving the at least two memory bank commands via multiple channels; prioritizing the at least two received memory bank commands on the basis of a static priority allocation; and further prioritizing the at least two commands having the same static priority on the basis of a dynamic priority allocation for the channels.
