Abstract
An electronic postal meter has an accounting unit with redundant nonvolatile random access memories controlled by a microprocessor system. The redundant random access memories have separate groups of address and data lines to minimize identical errors in data stored therein. The data transfer may occur at different times to and from the memories, with respect to any given byte of data. The system may incorporate redundant microprocessors, and critical parameters may be checked at periodic intervals in the main program of the accounting microprocessor system.
