- 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...

- You heard it hear first :)
