Object management in tiered memory systems

An apparatus, comprising:

• a plurality of memory devices comprising a first memory device of a first type and a second memory device of second type;
• and
• a memory controller coupled to the plurality of memory devices, wherein the memory controller is configured to determine a type of characteristic set of a plurality of memory objects to be written to one of the first memory device or the second memory device;
• wherein, a memory object of the plurality of memory objects is associated with a respective key stored in the first memory device and a respective value stored in the first memory device or the second memory device, wherein a determination of where the value is stored is based on the determined type of characteristic set;
• wherein, the respective key indicates a location at which the memory object is stored and the respective value represents data associated with the memory object;
• and
• wherein the respective key and the respective value comprise a respective key-value pair;
• and
• wherein the controller is further configured to:
• send the respective values of the plurality of memory objects to one of the first memory device or the second memory device to be stored;
• and
• send the respective keys of the plurality of memory objects to the first memory device;
• and
• wherein the plurality of memory objects are sent to the first memory device using a first protocol and to the second memory device using a different protocol.
