Subscriber interface between a FlexRay communication module and a FlexRay user and method of transmitting messages via such an interface

The invention relates to a subscriber interface (204) between a FlexRay communication chip (100), which is connected to a FlexRay communication link (101) over which messages are transmitted, and a message memory (300) for temporarily storing messages from the FlexRay communication link (101) or for the FlexRay communication link (101), and the FlexRay communication chip (100) associated with the subscriber (102). A particularly resource-saving and resource-saving connection of the subscriber (102) to the FlexRay communication chip (100) to enable it is proposed that the subscriber interface (204) comprises an array (800) for temporarily storing the messages. The arrangement (800) comprises at least one message memory (802) having a first connection (804) to the FlexRay communication chip (100) and a second connection (806) to the subscriber (102). The message memory (802) is preferably as a dual-ported RAM formed.
