Silicon circuits slowly degrade over time for a variety of reasons ranging from cosmic rays and general environmental radioactivity to creep, whisker growth, electrical power instability, contaminants, cracks, thermal fatigue, thermal and potential driven diffusion, oxidation, moisture penetration through plastic packaging, and simple mechanical stress induced by vibration, power cycling and even normal operation cycles. Just because it doesn't have any 'moving parts' doesn't mean it doesn't wear out: EVERYTHING wears out sooner or later. -- Benjamin Franz "All right, where is the answer?
