  • Patent number: 11137919
    Abstract: Disclosed are devices, method and/or systems for responding to a request for accessing a portion of a memory prior to completion of a requested operation to place the portion of the memory in an initialized state. In one example implementation, a memory controller may delay initiation of a write operation addressed to a particular portion of the memory until completion of a pending request to initialize the particular portion of the memory. In another example implementation, a memory controller may return values to service a request for a read operation comprising values representing an initialized state without accessing the particular portion of the memory responsive to a presence of a pending request to initialize the particular portion of the memory.

  • Patent number: 10866899
    Abstract: A method and apparatus for controlling data organization in a tiered memory system, where the system comprises a lower and higher bandwidth memories. Accesses to the tiered memory system by an action of a computing device in a first time interval are monitored to determine a first measure of bandwidth utilization, from which it is determined if the action is in a high bandwidth phase for which a first measure of bandwidth utilization is greater than an upper value. It is further determined, from confidence counters, if a monitored access is consistent with respect to the first instructions or with respect to a memory address of the access. Data associated with the access is moved from the lower bandwidth memory to the higher bandwidth memory when the action is in a high bandwidth phase, the access is consistent, and bandwidth utilization of the higher bandwidth memory is below a threshold.

  • Patent number: 10816289
    Abstract: A multi-column box magazine for rimmed ammunition cartridges of varied lengths has an elongated housing with a neck portion where cartridges are arranged in a single column and a mouth at an upper feed end through which cartridges are inserted and extracted. In a multi-column portion, cartridges are arranged in laterally alternating columns, and in a transition portion the alternating columns are transitioned into the single column as the cartridges are moved toward the mouth within the housing. A follower is biased by a spring toward the mouth. The multi-column portion has a forward interior surface limiting forward movement position of cartridges, which varies depending on individual cartridge length, and the neck portion having a forwardly sloped rearward wall which confronts the cartridge rim and shifts the cartridge forward, as needed, as cartridges are moved upwardly within the housing to the mouth.

  • Patent number: 10805978
    Abstract: A system, device and methodology for releasing a connection between user equipment (UE) and a node in a communications network is disclosed. The method includes, at the UE, responsive to an application layer indication that no further data is expected by the UE, receiving a RRC connection release message from the node and transmitting, from the UE, a radio link control (RLC) status message using RLC acknowledged mode (AM) to the node. An early connection release timer at the UE and node based on RLC AM parameters for a signal radio bearer (SRB) is started and upon expiry of the early connection release timer, the node releases the RRC connection. This obviates the need to wait a full 10 s per the 3GPP standard to release the connection during periods of poor radio connectivity, and reduces power consumption at the UE.

  • Patent number: 10797238
    Abstract: Subject matter disclosed herein may relate to construction of a correlated electron material (CEM) device. In particular embodiments, after formation of a film comprising layers of a transition metal oxide (TMO) material and a dopant, at least a portion of the film may be exposed to an elevated temperature. Exposure of the at least a portion of the film to the elevated temperature may continue until the atomic concentration of the dopant within the film is reduced, which may enable operation of the film as a correlated electron material CEM exhibiting switching of impedance states.

    Abstract: A method and apparatus are provided for automatic routing of messages in a data processing system. An incoming message at an input/output (I/O) interface of the data processing system includes a message identifier and payload data. Match information, including an indicator or whether the message identifier of the incoming message matches an identifier of a request in a receive queue (RQ), is used to determine a destination for the incoming message. The incoming message is forwarded to the determined destination. Information, such as payload size and RQ position, may be used to determine allocation of the payload within a cache or cache hierarchy.
