Abstract
A semiconductor circuit, in particular for use in an integrated module, has at least one operational assembly with a drive circuit, such as a microprocessor, and a data memory. The semiconductor circuit has at least one initialization assembly for testing and/or for initializing the operational assembly. A disconnectable connecting line connects the operational assembly to the initialization assembly. In order to increase reliability, the initialization assembly is permanently disconnected from the operational assembly, by disconnecting the connecting lines, after the semiconductor circuit has been completed. In order to make it more difficult to reactivate the disconnected connecting lines, the semiconductor circuit has a potential line connected to the initialization assembly and/or to the operational assembly in a region of the connecting line. The initialization assembly and/or the operational assembly are configured in such a way that, when the potential line is connected to the connecting line, the initialization assembly is placed in an inactive state.
