| 摘要 |
The invention relates to a module having a first integrated circuit and a second integrated circuit which are arranged on separate substrates, having a first output terminal and a second output terminal to which the first and second integrated circuits are respectfully connected in a parallel manner, and having a first selection terminal and a second selection terminal which are mutually separate and are connected to the first and second integrated circuits, respectively. A test circuit is provided in each of the integrated circuits to generate an error signal depending on whether an error occurred during a test operation, and an output circuit is provided in each of the integrated circuits to select the first output terminal or the second output terminal, depending on a selection signal that is applied to the respective selection terminal, for the purpose of outputting a state that indicates the error.
