Method and apparatus for the replacement of non-operational metal lines in DRAMS |
摘要 |
A semiconductor integrated circuit device including a redundant metal line for replacing a non-operational metal line for connecting to a circuit block. The invention further includes a method for decoupling a defective or otherwise non-operational conductive data line from a circuit block to which it is connected, and replacing the defective conductive data line with a redundant line by coupling it to the same circuit block. A spare conductive block is not needed. The redundant metal lines may be used in multiple levels of hierarchy within an integrated circuit device. |
