Abstract
Systems, methods, and devices implement counters with fault tolerance and power loss protection. Systems include a non-volatile memory device that includes a first counter configured to store a first plurality of data values representing a plurality of count operations, and a second counter configured to store a second plurality of data values representing an initiation and a completion of each erase operation performed on the first counter. Systems also include control circuitry configured to generate a count value based on a current counter value of the first counter, a current counter value of the second counter, and at least one physical parameter of the first counter.
