About TKey Memory One important aspect, when it comes to security in devices, is how data stored in memory, is protected.
Program Storage On the end user TKey, the entire FPGA design together with the firmware ROM is kept in the locked-down configuration memory (NVCM - Non Volatile Configuration Memory) within the FPGA chip. It’s not externally readable and only readable by the FPGA when configuring itself. This means the device secret (UDS) can’t be read, not even with the TKey programming board we provide.

We strongly believe that security products are better and even more secure when they are open. That way everyone can inspect the hardware and software design before choosing to use it.
