Abstract

A hierarchical memory device having multiple interfaces with different memory formats includes a Phase Change Memory (PCM). An input port and an output port connect the hierarchical memory device in a daisy-chain hierarchy or a hierarchical tree structure with other memories. Standard non-hierarchical memory devices can also attach to the output port of the hierarchical memory device.
