In one embodiment, an apparatus includes a memory and a scheduler. The scheduler is coupled to the memory and a memory controller. The memory stores a plurality of metadata requests. Each of the plurality of metadata requests is associated with one of a plurality of metadata priority levels. The scheduler schedules transmission of a first metadata request of the plurality of metadata requests to the memory controller based at least in part on a first metadata priority level associated with the first metadata request and a first bandwidth portion of a metadata request bandwidth. The first bandwidth portion is associated with the first metadata priority level. Other embodiments are described and claimed.

Embodiments of apparatuses, methods, and systems for scalable multi-key memory encryption are disclosed. In an embodiment, an apparatus includes a core, an encryption unit, and key identification hardware. The core is to write data to and read data from memory regions, each to be identified by a corresponding address. The encryption unit to encrypt data to be written and decrypt data to be read. The key identification hardware is to use a portion of the corresponding address to look up a corresponding key identifier in a key information data structure. The corresponding key identifier is one multiple key identifiers. The corresponding key identifier is to identify which one of multiple encryption keys is to be used to encrypt and decrypt the data.
