ABSTRACT:
A franking machine is disclosed in which the accounting memories are implemented by memory devices in which each storage location comprises a volatile and a non-volatile cell. During normal operation data is written to the volatile cells of the storage locations and in the event of a power down the data is transferred from the volatile to non-volatile cells. The volatile cells preferably are semi-conductor and the non-volatile cells are ferroelectric capacitative devices which retain their polarization without supply of power. The memory devices may provide storage for accounting data and other data processed by a micro-controller of the franking machine. In addition the memory device may be utilized to store other data which is not to be processed by the micro-controller. This other data includes program data and, in order to prevent this data being erased or over-written, gating circuits are provided to prevent write accesses by the micro-controller to areas of memory utilized for storing data which is not to be changed.
