发明名称 Semiconductor device with increased replacement efficiency by redundant memory cell arrays
摘要 A semiconductor memory device is disclosed that allows an increase in the replacement efficiency by redundant memory cell arrays. Redundant row address judging circuits output redundant row selection signals for differing banks, whereby redundant row selection signals are not outputted to other banks in cases in which row addresses of defective memory cells have been programmed to replace the word lines of a particular bank by a redundant memory cell array.
