IIRC, intel chips have had software modifiable microcode (or some portion thereof) that could render them useless for a good 10 years or more.

  Intel microcode lives in SRAM. It can't survive a power cycle, and so has to be loaded on every boot.

    Interesting. Can it be written during normal operation? Like giving up a couple opcodes for a better implementation of an important one?
