Abstract
In embodiments of the present invention improved capabilities are described for RFID tags with hardened memory, where the memory comprises a plurality of one time programmable (OTP) non-volatile memory locations for storing data, wherein the plurality of OTP non-volatile memory locations are configured to emulate a hardened memory system that retains data stored in the OTP non-volatile memory locations, wherein the data stored is retained after exposure of the RFID tag to an ionizing radiation exposure with an exposure level greater than 25 kGy.
