摘要： An integrated semiconductor memory has regular row and column lines, which can be replaced with redundant row and column lines in the event of a fault. Following initialization of the memory cells with an initialization data item, a data generator circuit writes an identification data item to the memory cells along a regular row or column line. A faulty regular row or column line is replaced with the associated redundant row or column line. Next, the initialization data item is written to memory cells along sound regular row or column lines and the respective identification data item is written to the memory cells along a faulty regular row or column line. Faulty regular row or column lines have the same data value in their memory cells as the redundant row or column lines replacing them.

摘要： The invention relates to a test method for determining a wire configuration for a circuit carrier having at least one component arranged thereon, where internal lines in the component are connected to component connections in a prescribed order, and where the component connections are wired to connections on the circuit carrier. According to the method, a respective prescribed test signal is applied to each internal line of the component using a controllable test signal generator integrated in the component. Output signals applied to the connections of the circuit carrier are tapped off. Thereafter, the respective output signals tapped off are identified with the corresponding test signals applied to the internal lines of the component using an external test apparatus for determining the wire configuration between the component connections and circuit carrier connections.

摘要： A method of testing internal signals of a memory for timing marginalities which may result in unstable operation includes: delaying internal address signals of the memory by an amount great enough so that data cannot be validly written to and read from memory locations which are accessed by address signals having timing marginalities which are delayed but small enough so that data can be validly written to and read from memory locations which are accessed by address signals not having such timing marginalities which are delayed. Data is then written to and read from memory locations which are accessed by delayed address signals, and a determination is made as to whether the data read from any memory location does not correspond with the data written to such memory location.
