The disclosure relates in some aspects to an apparatus that includes stages of a failure event counting circuit including an Nth stage where N refers to an arbitrary stage of the stages of the failure event counting circuit. The Nth stage may include an Nth fuse trigger circuit configured to receive an event detector signal indicative of a failure event, an Nth electronic fuse configured to disconnect a circuit path between a voltage source and a ground in response to the event detector signal, and an Nth delay circuit coupled to the Nth e-fuse and configured to cause a time delay for activating a subsequent stage of the failure event counting circuit in response to the Nth e-fuse disconnecting. In this aspect, each of the stages of the failure event counting circuit may be configured to use the respective e-fuse to record a discrete failure event.
