I'm curious what this process would be. My understanding was they'd typically have a small section of write-once fuses/PROM, and then some final process step to permanently program an ID into that area. That would mean the process to do so could possibly be recorded (or compromised), so I'm interested if there's a fabrication technique to reliably create random ROM sections.
Do you have any more info?
