Method to implement a monotonic counter with reduced flash part wear

摘要

A method of using a counter stored in flash memory includes providing a base value field, a selector field, and a plurality of increment fields. The base value field represents a base value for the counter, and the selector field indicating a first increment field of the plurality of increment fields. The method further includes changing a bit of the first increment field from an erased value to a written value to indicate a change in a value stored in the counter.
