Abstract

A system, memory hub device, method and design structure for providing an enhanced cascade interconnected memory system are provided. The system includes a memory controller, a memory channel, a memory hub device coupled to the memory channel to communicate with the memory controller via one of a direct connection and a cascade interconnection through another memory hub device, and multiple memory devices in communication with the memory controller via one or more cascade interconnected memory hub devices. The memory channel includes unidirectional downstream link segments coupled to the memory controller and operable for transferring configurable data frames. The memory channel further includes unidirectional upstream link segments coupled to the memory controller and operable for transferring data frames.
