Abstract
An electronic postage meter has two non-volatile memory devices, each of a different technology, CMOS battery-backed RAM and E.sup.2 PROM. The E.sup.2 PROM technology allows a limited number of rewrites. In order to provide real-time accounting in such a non-volatile memory over the life of the meter, a trip data counter is stored in a circular data store in addition to a separate account of other postage accounting data, including printwheel setting information. The trip data counter is used for calculations of postage meter register data. The separate account is updated at predetermined intervals using the trip counter data if necessary for data recovery.
