  • Patent number: 11537528
    Abstract: This disclosure provides techniques hierarchical address virtualization within a memory controller and configurable block device allocation. By performing address translation only at select hierarchical levels, a memory controller can be designed to have predictable I/O latency, with brief or otherwise negligible logical-to-physical address translation time. In one embodiment, address transition may be implemented entirely with logical gates and look-up tables of a memory controller integrated circuit, without requiring processor cycles. The disclosed virtualization scheme also provides for flexibility in customizing the configuration of virtual storage devices, to present nearly any desired configuration to a host or client.

  • Patent number: 11481144
    Abstract: A host stores “context” metadata for logical block addresses (LBAs) in a manner tied to physical location. Notwithstanding log-structured or copy on write processes, the host is then provided with immediate context when the host is called upon to assist a memory controller with data identified by physical location, for example, for memory reconfiguration, garbage collection, wear leveling or other processes. The metadata for example can provide the host with insight as to which data may be moved to enhance performance optimization and where that data can be placed. In one embodiment, the host writes back one or more references that span multiple layers of indirection in concert with write of the underlying data; in another embodiment, the context can point to other metadata.

  • Publication number: 20220338208
    Abstract: Aspects of the subject disclosure may include, for example, obtaining a first set of traffic load measurements associated with current traffic of a first RAT and a second set of traffic load measurements associated with current traffic of a second RAT, determining a respective weighted traffic load for each QoS level in a first set of QoS levels associated with the first RAT and for each QoS level in a second set of QoS levels associated with the second RAT, deriving a resource allocation ratio for the first and second RATs, and performing a resource allocation based on the resource allocation ratio to enable relative scheduling weights assigned to the QoS levels in the first set of QoS levels and the second set of QoS levels to be reflected in first RAT traffic and second RAT traffic over a DSS spectrum. Other embodiments are disclosed.
