Nonvolatile Memory

The nonvolatile memory within the TA100 device is split into three pieces:

Configuration

Memory:

In general, this area is expected to be written prior to the placement of the TA100 device on

the application board. Once the configuration is complete, this area must be locked to prevent

further modification and for proper device operation.

Shared Data

Memory:

This area can be used for keys, secrets, certificates, and/or data. The TA100 does not place

any requirements on the arrangement or distribution of items stored within this block other

than the overall limit on the space available to all the shared elements.

Dedicated Data

Memory:

Certain other items are stored within the device and are managed directly by various

commands.
