The scratchpad is an additional page that acts as a buffer when writing to memory. Data is first written to the scratchpad where it can be read back. After the data has been verified, a copy scratchpad command transfers the data to memory. This process ensures data integrity when modifying the memory. A 48-bit serial number is factory lasered into each DS1992 to provide a guaranteed unique identity that allows for absolute traceability. The durable MicroCan® package is highly resistant to environmental hazards such as dirt, moisture, and shock. Its compact coin-shaped profile is self-aligning with mating receptacles, allowing the DS1992 to be easily used by human operators. Accessories permit the DS1992 to be mounted on almost any surface including plastic key fobs, photo-ID badges, and PC boards.

Applications include access control, work-in-progress tracking, electronic travelers, storage of calibration constants, and debit tokens.
