Rugged portable memory systems for demanding OEM applications.

Our products utilize industry-standard memory (EEPROM, NOR Flash, USB Flash, SD) and solid over-molded construction, resulting in a portable memory device that is rugged enough for the most demanding applications--yours.

NEW! Datakey CryptoAuthentication™ Memory Tokens

CryptoAuthentication™ memory tokens take the security features of Microchip's ATSHA204A and ATECC608A CryptoAuthentication™ ICs and put them into a physically robust portable memory device.


When you want to use a USB flash drive, but your application calls for a more robust solution, count on RUGGEDrive™ to deliver.


If you can talk to a serial EEPROM IC, you already know how to talk to our serial memory products. Easy to integrate. Supported for decades.


Tested to MIL-STD-810 environmental standards, the Bar Series memory tokens and receptacles provide reliable operation wherever the mission demands.
