There’s also meta-stability. If a value is snapshotted half way through it changing, it may occasionally result in the output not being one or zero, but some ‘half’ value. Depending on the circuits using that result, it may be interpreted as either 1 or 0 — and maybe different parts of the circuit will use different interpretations. Such intermediate states are only meta-stable, and will flip to a firm 1 or 0 at some indeterminate time later, possibly propagating the problem.

In the early days of personal computing CPU bugs were so rare as to be newsworthy.
