But like I said, I really have no idea. D.J., Dallas Semi did something like this with a serially encoded id chip. The chip was dirt cheap, so it must have been fairly simple to program. Obviously they could have used PROM or EERAM, but those do have a life span... maybe it was just simple fused logic. Regardless, it was probably serialized during the testing. True, it would add a few cents to the tester time, but as processors get more and more expensive it wouldn't be such a bad idea to have them forever marked and traceable...
