Excerpt
Excerpt It has been shown that any desired interconnection pattern can be programmed. This flexibility can also be used to correct manufacturing defects. If spare pads and spare net lines are available, a given set of defects can be neutralized simply by not using any affected pads or nets. Since it is known that certain amorphous chalcogenide materials cannot only be switched into the conductive state but also back into the non-conductive state, the usage of such materials would not only allow for programming but also for reprogramming. Reprogramming can then be used to neutralize even such defects which are discovered or which occur only after the initial programming.
