Buffered Memory Module with Multiple Memory Device Data Interface Ports Supporting Double the Memory Capacity

摘要

A memory system is provided that enhances the memory bandwidth available through a memory module. The memory system includes a memory controller and at least one memory module coupled to the memory controller. In the memory systems, each memory module comprises at least one memory hub device integrated in the memory module. In the memory system, each memory hub device in the memory module comprises a first memory device data interface that communicates with a first set of memory devices and a second memory device data interface that communicates with a second set of memory devices. In the memory system, the first set of memory devices which are separate from the second set of memory devices are communicated with by the memory hub device via the separate first and second memory device data interfaces.
