摘要
A mechanism is provided for using a cache that is embedded in a memory hub device to replace failed memory cells. A memory module comprises an integrated memory hub device. The memory hub device comprises an integrated memory device data interface that communicates with a set of memory devices coupled to the memory hub device and a cache integrated in the memory hub device. The memory hub device also comprises an integrated memory hub controller that controls the data that is read or written by the memory device data interface to the cache based on a determination whether one or more memory cells within the set of memory devices has failed.
