  • Publication number: 20250254985
    Abstract: A structure including a first fin-type field effect transistor (finFET) in a first semiconductor fin. The first finFET includes a channel region between a first source/drain (S/D) region and a second S/D region; and a gate all around (GAA) structure. The GAA structure includes an outer gate region over the channel region and a buried gate region under of the channel region and extending between the first S/D region and the second S/D region. The outer gate region and the buried gate region each include a gate metal layer and a gate dielectric layer. The gate dielectric layer is thicker in the buried gate region than in the outer gate region.

  • Patent number: 12382301
    Abstract: Systems, methods, and computer-readable media herein provide for adjustment of a spectrum sharing allocation between devices operating on 5G and/or 6G technologies. An inter-operator scheduler receives common signals associated with 5G and/or 6G devices and determines time and/or frequency divisions and configurations to a shared technology spectrum to allocate spectrum resources. In response to determining an allocation of the shared spectrum, the shared spectrum can be efficiently shared among 5G and 6G devices in a dynamic and flexible manner.

  • Patent number: 12360923
    Abstract: Data-driven intelligent networking systems and methods are provided. The system can accommodate dynamic traffic while applying injection limits to different traffic classes at an ingress edge port. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow can be acknowledged after reaching the egress point of the network, and the acknowledgement packets can be sent back to the ingress point of the flow along the same data path. Furthermore, an edge switch can dynamically allocate the ingress port bandwidth among the traffic classes that are active at a given moment.

  • Patent number: 12341686
    Abstract: A network interface controller (NIC) capable of efficiently utilizing an output buffer is provided. The NIC can be equipped with an output buffer, a host interface, an injector logic block, and an allocation logic block. The output buffer can include a plurality of cells, each of which can be a unit of storage in the output buffer. If the host interface receives a command from a host device, the injector logic block can generate a packet based on the command. The allocation logic block can then determine whether the packet is a multi-cell packet. If the packet is a multi-cell packet, the allocation logic block can determine a virtual index for the packet. The allocation logic block can then store, in an entry in a data structure, the virtual index, and a set of physical indices of cells storing the packet.

  • Publication number: 20250173338
    Abstract: Dynamic scaling may be performed for a distributed database according to a cluster-wide resource allocation. Performance metrics for different query processing nodes of a distributed database system are obtained and evaluated to make scaling decisions for the database system. Scaling operations may include increasing or decreasing database capacity units allocated to a query processing node according to the cluster-wide allocation or adding a new query processing node to the cluster, the new node being allocated database capacity units from the cluster-wide allocation of database capacity units.
