A semiconductor memory circuit includes a plurality of memory cell arrays arranged in rows and columns. A decoder circuit selects a predetermined number of memory cell arrays from among the plurality of the memory cell arrays. Sense amplifiers sense data read from selected memory cell arrays. The plurality of memory cell arrays are grouped into a first type of memory cell arrays each having a redundant memory cell and a second type of memory cell arrays each having no redundant memory cell.
