ABSTRACT:
A memory system is provided that manages thermal conditions at a memory device level transparent to a memory controller. The memory systems comprises a memory hub device integrated in a memory module, a set of memory devices coupled to the memory hub device, and a first set of thermal sensors integrated in the set of memory devices. A thermal management control unit integrated in the memory hub device monitors a temperature of the set of memory devices sensed by the first set of thermal sensors. The memory hub device reduces a memory access rate to the set of memory devices in response to a predetermined thermal threshold being exceeded thereby reducing power used by the set of memory devices which in turn decreases the temperature of the set of memory devices.
