It might actually use a traditional fuse block, where at some point in the packaging/testing process, you literally apply a sufficiently high voltage that you can permanently 'set' some part of it (whether that's actually melting a tiny wire, I'm not sure). But that's basically just programming a ROM that gets read in at boot time, and sets a bunch of logic on the chip to route around the bad parts. You could just use an external EEPROM to track that info too, and it would basically work the same.
- andrewf 5y ago20 years ago people were overclocking AMDs by drawing on them with pencil: http://www.ocmelbourne.com/tutorials/PencilTrick/ http://www.ocmelbourne.com/tutorials/PencilTrick/ This last decade people soldered resistors onto cheaper NVIDIA cards, to make them behave as more expensive NVIDIA cards: https://www.eevblog.com/forum/general-computing/hacking-nvidia-cards-into-their-professional-counterparts/?PHPSESSID=3kesesdcd2gp8tftrkiihn6ef2 https://www.eevblog.com/forum/general-computing/hacking-nvid... So chipmakers have an incentive to bury the process in the chip and make it irreversible.
