The present invention relates to the field of devices which store data for a period of time. In one form, the invention relates to devices which store data in which the data store is subject to periodic and/or relatively short power outages. In one example, the invention relates to a radio frequency identification ("RFID") transponder, and more particularly to a RFID transponder that is used in orientation independent applications. Other applications of the present invention are to devices used where supply power is intermittent. In a first aspect of embodiments described herein there is provided a .method of and/or device comprising a memory adapted to store data, a supply of power adapted to provide supply power to the memory, a path of leakage, the leakage path serving, over time, to diminish the integrity of data stored in the memory, and a leakage attenuator adapted to selectively attenuate the rate of leakage. |
