    摘要: Multiple dies can be stacked in what are commonly referred to as three-dimensional modules (or “stacks”) with interconnections between the dies, resulting in an IC module with increased circuit component capacity. Such structures can result in lower parasitics for charge transport to different components throughout the various different layers. In some embodiments, the present invention provides efficient power distribution approaches for supplying power to components in the different layers. For example, voltage levels for global supply rails may be increased to reduce required current densities for a given power objective.

    摘要: 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.
