Abstract: A memory controller operable for selective memory access to areas of memory exhibiting different attributes leverages different memory capabilities that vary access speed, retention time and power consumption, among others. Different areas of memory have different attributes while remaining available to applications as a single contiguous range of addressable memory. The memory controller employs an operating mode that identifies operational priorities for a computing device, such as speed, power conservation, or efficiency. The memory controller identifies an area of memory based on an expected usage of the data stored in the area, for example an access frequency indicating future retrieval. The memory controller therefore selects areas of memory based on the operating mode and the expected usage of data to be stored in the area according to a heuristic that favors areas of memory based on those exhibiting attributes having a high correspondence to the expected usage of the data.

Abstract: Dynamic operations for operations for 3D stacked memory using thermal data. An embodiment of a memory device includes memory having multiple coupled memory elements and multiple thermal sensors, including a first thermal sensor in a first area of the memory stack and a second thermal sensor in a second area of the memory stack. A memory controller is to provide operations to modify thermal conditions of the memory elements based at least in part on thermal information generated by the thermal sensors.
