Abstract: A circuit configuration for driving a programmable link, for example a fuse, is specified, having a drive circuit for driving the fuse in a manner dependent on a signal present at the data input, and also a volatile memory, whose output is preferably directly connected to the data input of the drive circuit. A circuit configuration for particularly fast and simple programming of fuses, in particular electrically programmable fuses, is thereby specified.

Abstract: An integrated circuit includes a self-test device which is provided for executing a self-test of the integrated circuit and which has a control output. A program memory is connected to the self-test device for storing at least one test program supplied from outside the integrated circuit. The test program is run by the self-test device during execution of a self-test. The self-test device controls loading of a respective test program to be run into the program memory from outside the integrated circuit through the control output thereof.

Abstract: Electrical fuses (1) and a test fuse (4) connect to a test circuit (7) so that data in the electrical fuses and the test fuse can be read out into the test circuit, which is designed in such a way that it determines whether an item of data in one of the electrical fuses is defective. Data written in the electrical fuses and the electrical test fuse is processed according to a function for identifying whether data has been written incorrectly in one of the electrical fuses. An Independent claim is also included for a method for recognizing a defective electrical fuse in an integrated circuit.

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.
