摘要：
Regular memory cell arrays are arranged in divided regions in three rows and three columns except for the region located at the second row and the second column. The region located at the intersection of the second row and the second column is provided with a redundant memory cell array. The replacement operation of the regular memory cell arrays with the redundant memory cell array is provided for each memory cell block.
