Abstract
PURPOSE: To provide diagnosing and stand-by circuits for increasing the ratio of an actually-required basic circuit in IC's.
CONSTITUTION: A diagnosing circuit 60 and stand-by circuits 51W53 are provided in basic circuits 40W45. In normal operation, only circuits 40W45 and 60 operate to check the logic of said circuits 40W45. Next, if the trouble of said circuit 41 for example is detected by said circuit 60, the interchange of said circuits 41 and 51 is instructed means of the signal group 1000 from said circuit 60 so that said circuits 41 and 51 are interchanged with each other. Consequently, the functions of the whole structure of an IC are restored so that the reliability thereof can be raised. Further, when said IC is made of a plurality of circuits with the same functions, the ratio of said basic circuit to a redundant circuit and the concentration of a required circuit in said IC can be increased.
