Datakey Electronics (Savage, MN) has confirmed that its GammaSafe memory tokens survive e-beam sterilization with no data loss. The GammaSafe memory token also supports sterilization by ethylene oxide (EtO) gas, autoclave, or gamma radiation, and allows medical device manufacturers to electronically limit the use of their disposables by tracking usage information on the memory token's non-volatile memory. The memory token contains four kilobits of non-volatile, reprogrammable memory, functions similarly to an EEPROM device, and uses an SPI serial interface for communications.
