According to one general aspect, an apparatus may include a processor, a heterogeneous memory system, and a memory interconnect. The processor may be configured to perform a data access on data stored in a memory system. The heterogeneous memory system may include a plurality of types of storage mediums. Each type of storage medium may be based upon a respective memory technology and may be associated with one or more performance characteristics. The heterogeneous memory system may include both volatile and non-volatile storage mediums. The memory interconnect may be configured to route the data access from the processor to at least one of the storage mediums based, at least in part, upon the one or more performance characteristic associated with the respective memory technologies of the storage media.
