| Zusammenfassung: | Methods and systems for measuring degradation includes measuring an initial electrical characteristic of a test device in a ring oscillator that includes multiple oscillator stages and a test stage having a delay stage and the test device. The ring oscillator is operated for a period of time. The electrical characteristic of the test device is measured after operating the ring oscillator. A level of degradation in the test device is determined using a processor based on the measurements of the electrical characteristic of the test device. |
