Abstract
One embodiment of the invention provides an adapter card for connection to a data bus in a data processing unit. The adapter includes a DDR interface for connection of a DDR memory module, a memory unit for storing test mode data, a switching device, which, in a first switching state, connects the data bus to the DDR interface and, in a second switching state, decouples the DDR interface from the data bus and connects the memory unit to the DDR interface such that test mode data may be transmitted to a connected DDR memory module to call up a test mode in the DDR memory module. The adapter also includes a control circuit with a trigger input to control the switching device between the switching states depending on a trigger signal.
