Abstract
An electronic postage meter includes two non-volatile memories. One of the non-volatile memories is utilized for storing in historical sequence in respective registers the transaction information for each of a predetermined number of transactions which have occurred prior to the last transaction. This memory is accessed at the time of each transaction. The real-time transaction information may be sequentially written over the earliest information in the registers. The other non-volatile memory stores cumulative data upon power-down.
Claims9
A method for storing different historical information reflecting the postage transactions of an electronic postage meter, comprising the steps of:
- providing a first non-volatile memory;
- providing a second non-volatile memory having a larger data storage capacity than the first non-volatile memory with individually addressable memory locations for storing information regarding each postage meter transaction on a real time basis;
- writing cumulative historical information corresponding to the postage meter transactions into the first non-volatile memory during each power down cycle of the meter;
- sequentially writing historical information corresponding to postage meter transactions in respective different memory locations in the second non-volatile memory in real time as each postage meter transaction occurs to provide a historical record of each postage transaction so that two different records of historical information regarding the postage transactions are provided in non-volatile memory with the first non-volatile memory providing a cumulative historical record reflecting the postage transactions prior to a power down cycle and the second non-volatile memory providing a sequential historical record of each individual postage transaction.
In an electronic postage meter, a system for storing different historical information reflecting the postage transactions , comprising:
- first non-volatile memory means;
- second non-volatile memory means having a larger data storage capacity than said first non-volatile memory means with individually addressable memory locations for storing information regarding each postage meter transaction on a real time basis;
- microprocessor means for writing cumulative historical information corresponding to the postage meter transactions into said first non-volatile memory means during each power down cycle of the meter and sequentially writing historical information corresponding to each postage meter transaction in respectively different memory locations in said second non-volatile memory means in real time as each postage meter transaction occurs to provide a historical record of each postage transaction so that two different records of historical information regarding the postage transactions are provided in non-volatile memory with said first non-volatile memory means providing a cumulative historical record reflecting the postage transactions prior to a power down cycle and said second non-volatile memory means providing a historical record of each individual postage transaction.
