Abstract:
A semiconductor component, comprising:a semiconductor chip having a main surface and a plurality of pads, said pads not being solely for testing;an electronic circuit formed in or on said main surface of said semiconductor chip and electrically connected to said pads;said electronic circuit being operable in a test mode, in which an external test signal is applied to a predetermined one of said pads, and in an operating mode, in which operating signals are applied to one of said pads; anda switching device connected to at least one of said pads, said switching device switching a function of at least one of said pads from the test mode to the operating mode, said switching device having inputs and an output, one of said inputs not connecting-through, said switching device switching a signal applied to one of said inputs in the test mode from one of said pads controlled by a test mode signal, to said output and switching a signal applied on a further one of said inputs by a further pad in the operation mode to said input not connecting-through in the test mode but guided to the electronic circuit as a test signal for testing relevant circuit parts.
