  • Patent number: 6715118
    Abstract: In the configuration, the module can “learn” one or more time intervals from the external tester and then repeat them internally or compare them to its own internally measured time intervals, for instance, for the purpose of evaluating whether the module in question has crossed a time specification value or remains below the value. The module can also measure and store one or more internal time intervals and transmit them to the external tester in digital or analog form.

  • Patent number: 6557130
    Abstract: The memory device of a semiconductor chip is tested with a BIST circuit. The configuration and the method store the test results obtained by the BIST circuit. The test results are stored in the sense amplifiers of the memory device. In addition, it also possible for test programs for the BIST circuit to be stored in the sense amplifiers.

  • Patent number: 6415406
    Abstract: An integrated circuit incorporating a self-test device and a method for producing a self-testing integrated circuit. The integrated circuit has a program memory with at least one external terminal for loading external test programs. The integrated circuit has a self-test device connected to the program memory, the self-test device executing program commands of a test program loaded into the program memory, the program commands succeeding one another in address terms, for carrying out a self-test of the circuit. The self-test device has an interrupt signal input, through which the self-test device interrupts the test program that is currently being executed by not executing the respective succeeding program command in address terms. Rather, it executes a program jump within the test program, the program jump being triggered by the interrupt signal.
