The described counter employs an event counter module that counts events that are generated by various event generators within the system. One type of event that can be counted by the described counter is a state change. In various implementations, the event counter module, when employed as a state change counter module, includes a state change counter that counts state changes, and a journal mode component which provides journaling functionality which makes it possible to accommodate large numbers of state changes while, at the same time, recover the counter in the event of a system failure. In at least some embodiments, one or both of the state change counter and the journal mode component are implemented using NOR flash memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Monotonically increasing persistent counters","description":"A monotonically increasing persistent counter is described that is persistent across reboots of a system in which it is incorporated.
