摘要 |
A semiconductor device such as a DRAM with many signal line circuits is also provided with a redundancy circuit and is so structured that when one of the signal line circuits is defective and the fuse contained by such a defective signal line circuit is cut off to inactivate it, an input signal which would select the inactivated signal line circuit will automatically select the redundancy circuit. |
