ABSTRACT:
A method and apparatus for reducing the accounting loss in the case of catastrophic failure of a microprocessor in an electronic postage meter is disclosed. In accordance with the invention a counter, preferably a ring counter, is implemented in a non-volatile memory (NVM). The ring counter is incremented each time a predetermined amount is transferred in an accounting register of the meter. In the ring counter, a specific location of NVM is erased and the next number in sequence is written into the same location upon the transfer. The ring counter field is easily interpreted by a visual inspection for determining the total amount transferred. The method and apparatus in accordance with the invention provides extremely fast transfer time, exhibits high redundancy with ease of interpretation, and overcomes the problem of read/write degradation limitations heretofore imposed by conventional MNOS non-volatile memories.
