ABSTRACT:
Apparatus, systems, and methods may operate to receive from a requesting device, at a memory device, a request to access a memory domain associated with the memory device, and to deny, by the memory device, the request if the memory domain comprises any part of a secure domain, and the requesting device has not asserted a secure transfer indication. Additional operations may include granting the request if the memory domain comprises some part of the secure domain and the requesting device has asserted the secure transfer signal, or if the memory domain comprises only a non-secure domain. Additional apparatus, systems, and methods are disclosed.
