Abstract:
Embodiments of the invention relate to a state-monitoring memory element. The state-monitoring memory element may be implemented by degrading an input voltage supply to the state-monitoring memory element across a diode and/or a transistor. One or more current sources may be used to stress the state-monitoring memory element. A logic analyzer may be used to analyze the integrity of the state-monitoring memory element and trigger appropriate actions in the IC, e.g., reset, halt, remove power, interrupt, responsive to detecting a failure in the state-monitoring memory element. Multiple state-monitoring memory elements may be disturbed in different locations on the IC for better coverage.
