摘要:
A voltage regulator for one or more dies in a multi-stack integrated circuit includes an inductor located on a die, a voltage controller that is electrically coupled to the inductor and is also located on the die, and a capacitor that is electrically coupled to the inductor and the voltage controller and is also located on the die. The inductor defines an interior space and the voltage controller and the capacitor are located within the interior space of the inductor. The inductor can be a lateral inductor or a through layer via inductor. The multi-stack integrated circuit may have multiple dies. A voltage controller may be electrically coupled to each of the dies, although it may be located on only one of the dies. Alternatively, separate voltage controllers may be electrically coupled to each of the multiple dies and may be located on each of the respective dies.

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.

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.
