SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a semiconductor circuit device of which manufacturing is simple and in which relieving defect can be performed under high reliability. SOLUTION: This device has first and second memory matrix including plural memory cells respectively, a relief address holding circuit including plural elements for storing a relief address for changing so that a memory cell of the second memory matrix is selected instead of a memory cell of the first memory matrix, a decoder selecting a memory cell from the first memory matrix when an address signal does not coincides with the relief address and selecting a memory cell from the second memory matrix when the address signal coincides with the relief address, and a pad applying voltage required for storing the relief address in the element. And it is prevented that a potential level of the pad is made unstable.
