Devices which store data for a period of time. In one form, devices store data in which the data store is subject to periodic and/or relatively short power outages. In one example, a radio frequency identification ('RFID') transponder, and more particularly, a RFID transponder that is used in orientation independent applications, is disclosed. Other applications are directed to devices used where a supply power is intermittent. In a first aspect of embodiments described herein, there is disclosed a method of and/or device that includes 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.

Device having data storage

A fast block write command includes providing an RFID tag having a memory, and using a stored address pointer to point to a known address in the memory, wherein the stored address pointer points to a starting address at a known safe block in the memory. The method is performed without an intermediate buffer. The received data is written to the known safe block and a cyclic redundancy check is computed on the received data. If the cyclic redundancy check matches, the received data is retained and the stored address pointer is updated. If the cyclic redundancy check does not match, the stored address pointer is kept for a future write operation. Further block writes can be disallowed after an initial successful block write.
