Abstract
A functional unit of a device is associated with a secret. Data stored in a memory location of the device is encrypted using the secret. The memory location of the device is accessible to other functional units; but without knowledge of the secret, the stored encrypted data is useless. The sharing of the secret creates a secure path between memory locations and functional units of the device while maintaining a unitary memory architecture. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
