ABSTRACT:
At least first and second IC-chip equivalent regions having functions available from conventional one-chip IC device are formed on a single semiconductor substrate. An output of the second region is supplied to an input terminal of the first region. The output of the second region is also delivered at an external terminal in response to a test signal through a multiplexer or a bidirectional buffer.
