Selective memory mode authorization enforcement

A system, comprising:

• a central processing unit;
• and
• memory interface logic having a memory and mode control logic configured to receive a memory transaction request and memory mode selection data associated with the memory transaction request and to perform a memory transaction request in a selected memory mode of operation of a plurality of potential memory modes of operation, if the selected memory mode of operation is enabled, said mode control logic including:
• a mode authorization classification structure for a memory mode of operation of the plurality of potential memory modes of operation of the mode control logic, wherein a mode authorization classification structure is configured to indicate whether an associated memory mode of operation is authorized;
• memory mode authorization logic configured to compare memory mode selection data associated with a memory transaction request to a mode authorization classification structure to determine if a selected memory mode associated with a memory transaction request is authorized;
• and
• memory mode enablement logic configured to enable the mode control logic to operate in a selected memory mode associated with a memory transaction request if it is determined that the selected memory mode associated with the memory transaction request is authorized.
