Or there is dielectric breakdown. And anytime something breaks down, there is an avalanche of new things you have to worry about. A lot of aging models advanced in an era where electronics were used sporadically. Now chips are running all the time. Inside of a chip, blocks are heating up, so aging is accelerated. From that you get all types of weird phenomena. A lot of companies have not revised their aging models, either. They assumed these devices would last three to four years, but they may fail sooner. And given that design margins from the beginning can be flimsy, aging can throw them off.”
