In one embodiment, different metal layers are used for power stripes that are operable to connect to voltage sources to supply different voltage signals, which allows some or all of the power stripes to have a larger width. Additionally or alternatively, fewer metal stripes are used for signals in a metal layer to allow the power stripe in that metal layer to have a larger width. The larger width(s) in turn increases the total area of the power stripe(s) to reduce the IR drop across the power stripe. The various power routings include connecting metal pillars in one metal layer to a power stripe in another metal layer, and extending a metal stripe in one metal layer to provide additional connections to a power stripe in another metal layer.

    Abstract: Embodiments of the invention provide systems and methods for managing processing, memory, storage, network, and cloud computing to significantly improve the efficiency and performance of processing nodes. More specifically, embodiments of the present invention are directed to an instruction set of an object memory fabric. This object memory fabric instruction set can be used to provide a unique instruction model based on triggers defined in metadata of the memory objects. This model represents a dynamic dataflow method of execution in which processes are performed based on actual dependencies of the memory objects. This provides a high degree of memory and execution parallelism which in turn provides tolerance of variations in access delays between memory objects. In this model, sequences of instructions are executed and managed based on data access. These sequences can be of arbitrary length but short sequences are more efficient and provide greater parallelism.

  • Patent number: 11609816
    Abstract: Multiple independent point-to-point memory channels are operated, by at least one controller, in parallel to form a wider memory channel. The memory components on these point-to-point channels include the ability to connect to multiple (e.g., 2) instances of these independent memory channels. The controller operates multiple instances of the wider channels with the memory components configured in a clamshell mode. A single memory component is also operated in clamshell mode to provide error correction code information, independently of the other wider channels, to multiple instances of the wider memory channel.
