Abstract

An on-die early lifetime failure detection system with a reliability mechanism isolation circuit provides an early lifetime failure detection. The system measures and monitors reliability at time-0 (t0) and end-of-life. The measurements enable detection of latent reliability or marginality issues during the lifetime of the product. The system includes: a stress controller to adjust voltage for a power supply and voltage for a ground supply in accordance with one or more sensors; and an aging detector circuitry coupled to the stress controller, wherein the aging detector circuitry comprises a ring oscillator having delay stages, wherein each delay stage comprises an aging monitor circuitry, wherein the stress controller to adjust voltage for a power supply and voltage for a ground supply of the delay stage.
