4 Nonvolatile Memory

The nonvolatile memory within the TA101 device is split into three pieces:

Configuration Memory:

The configuration memory is used to enable various features and functions for a given application. In general, this area is expected to be written prior to the placement of the TA101 device on the application board. When the configuration is complete, it is recommended that this area be locked to prevent further modification.

Shared Data Memory:

The shared data memory area can be used for storing keys, secrets, certificates and/or data. The TA101 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:

The dedicated data memory stores the 8-byte unique serial number of and software revision information associated with the device.
