ABSTRACT:
A system for the nonvolatile storage of data, such as a postage meter system, employs a microcomputer coupled to two nonvolatile memories. The first nonvolatile memory requires data be applied to the nonvolatile data terminals for more than a predetermined time for data to be written into said nonvolatile memory while the second nonvolatile memory is of a type wherein data applied to the second nonvolatile memory data terminals for less than the predetrermined time is sufficient for data to be written into the second nonvolatile memory. The microcomputer operates under control of a program store to apply data to the first nonvolatile memory data terminals for at least a predetermined time under particular operating conditions and under other operating conditions to applying data to the nonvolatile memory data terminals and during the predetermined time to the second nonvolatile memory terminals.
