Semiconductor integrated circuit device provided with a self-testing circuit for carrying out an analysis for repair by using a redundant memory cell

摘要

A memory cell array is divided into a first and second sub-memory cell arrays. A built-in self-testing circuit is provided with an address replacement determining circuit which is installed in each of the first and second sub-memory cell arrays, and which, assuming that a selection of a memory cell from the first and second sub-memory cell arrays and a replacement thereof to a preliminary memory cell can be carried out mutually in an independent manner, makes a determination as to which preliminary memory cell is used for replacement, and outputs the result of determination.
