    摘要: A circuit arrangement can have a number of integrated circuit components, which are arranged on a carrier substrate. A reception circuit for receiving a control signal can be coupled to one of the connection pads on the input side and can be connected to each of the circuit components on the output side. A bridging circuit controlled by a test mode signal can electrically bridge the reception circuit. In a testing method, a plurality of connection pads can be connected to a first potential and at least one of the connection pads can be connected to a second potential. The bridging circuit can be activated and the current measured, by a test arrangement, at the at least one of the connection pads. Inspection for leakage currents in connections between input-side reception circuits and the circuit components can be measured.

    摘要: A test arrangement with a test memory chip and a control device is provided. Error correction data are stored in the test memory chip with the aid of the control device. In the case of an error event, it is ascertained whether the error occurred on the error correction chip. If so, the memory controller compares the data stored in the error correction chip with the data of the auxiliary memory. The address of the error correction chip can be deduced from the address of the auxiliary memory, thereby enabling unambiguous addressing of a defective memory cell of the error correction chip.

    摘要: An integrated semiconductor memory device includes a first memory zone, a second memory zone, first address connections and a second address connection. A second address signal present at the second address connection specifies the access to the first or second memory zone, whereas it is specified via first address signals at the first address connections which memory cell is accessed within the first or second memory zone. In a first memory configuration, all address connections are driven externally with address signals and the access to a memory cell in the first or second memory zone is controlled. In a second memory configuration, only the first address connections are driven externally whereas a signaling bit in a mode register regulates the access to the first or second memory zone. This provides for access to the second memory zone even if there is no possibility of externally driving the second address connection.
