  • Publication number: 20250063958
    Abstract: The invention is directed to a phase-change memory (PCM) device. The device includes an electrically insulating material and a PCM cell, which is embedded in the electrically insulating material. The PCM cell includes a phase-change material layer (or PCM layer, for short), e.g., a layer including a germanium-antimony-tellurium alloy. The PCM layer has a top surface, a bottom surface, and a side surface linking the top surface and the bottom surface. The PCM cell further includes an outer electrode, which contacts the side surface of the PCM layer. That is, the outer electrode laterally caps the PCM layer. The PCM cell further includes a heater extending at least partially through the PCM layer, transversely to the top surface and the bottom surface of the PCM layer, to contact the PCM layer.

  • Publication number: 20250017023
    Abstract: Semiconductor devices and methods for forming the semiconductor devices are described. A semiconductor device can include a first electrode, a storage node, a second electrode and a film layer. The storage node can include phase change material deposited on top of the first electrode. The film layer can be deposited on top of the storage node and connected in a closed circuit. A voltage difference among the first electrode, the second electrode and the film layer can dictate a threshold voltage that triggers a phase change of the phase change material. An amorphous volume in the storage node can be dependent on a structural arrangement of the first electrode, the second electrode and the film layer with respect to the storage node.

  • Patent number: 12166687
    Abstract: Systems and methods for building service templates that allow for an agentless, data-driven and stateful automation of a provisioning of services to mobile network customers. Data associated with a request to create a target schema object class for a device and protocol are received. Based on the device and protocol information, a set of data fields associated with CRUD semantics is retrieved from either a database or from user provided data. A decorated target object class is created based on the requested target schema object class. A subrecipe is created including the decorated target object class, and one or more other decorated target object classes. A recipe is processed for transmission to an execution engine to form a service instance, the service instance being customizable by an operator for a specific network device such that the service instance data fields that are not pre-filled can be customized by the operator.

  • Patent number: 12105985
    Abstract: The invention is notably directed to a method of processing data in-memory. The method applies electrical signals to at least two input lines, which correspond to at least two rows. These two rows include at least one of the K rows and at least one of the L rows. This causes to obtain output signals in output of the M output lines, wherein the output signals depend on target values and operand values, in accordance with data stored across said at least two rows. Finally, the output signals are read out and a transformation operation is concurrently performed, in-memory, on the target values based on the operand values. This way transformed data are obtained by way of in-memory processing. The transformation may for instance be a cryptographic operation; the operand data may encode a cryptographic key. The invention is further directed to related apparatuses and systems, notably cryptographic service systems.

  • Patent number: 11665984
    Abstract: A projected memory device includes a carbon-based projection component. The device includes two electrodes, a memory segment, and a projection component. The projection component and the memory segment form a dual element that connects the two electrodes. The projection component extends parallel to and in contact with the memory segment. The memory segment includes a resistive memory material, while the projection component includes a thin film of non-insulating material that essentially comprises carbon. In a particular implementation, the non-insulating material and the projection component essentially comprises amorphous carbon. Using carbon and, in particular, amorphous carbon, as a main component of the projection component, allows unprecedented flexibility to be achieved when tuning the electrical resistance of the projection component.

  • Patent number: 11665985
    Abstract: A memory device enabling a reduced minimal conductance state may be provided. The device comprises a first electrode, a second electrode and phase-change material between the first electrode and the second electrode, wherein the phase-change material enables a plurality of conductivity states depending on the ratio between a crystalline and an amorphous phase of the phase-change material. The memory device comprises additionally a projection layer portion in a region between the first electrode and the second electrode. Thereby, an area directly covered by the phase-change material in the amorphous phase in a reset state of the memory device is larger than an area of the projection layer portion oriented to the phase-change material, such that a discontinuity in the conductance states of the memory device is created and a reduced minimal conductance state of the memory device in a reset state is enabled.

  • Patent number: 11563635
    Abstract: Systems and methods for rollback of model-based provisioned network device configuration including a memory capable of storing a model-based provisioned data template that includes a data template sequence. Data associated with a request to transmit a target object request message are received and transmitted following a retrieval message that determines pre-configuration data of the target device. The pre-configuration data is stored and the target object request message is sent specifying CRUD semantics. A notification is received indicating an outcome of the execution and, if the execution outcome is unsuccessful, a rollback stack is retrieved that specifies CRUD semantics and the pre-configuration parameters are retrieved to restore the target device to a pre-request state. If the execution outcome is successful, a second target object request message is retrieved from a list of target devices.

  • Publication number: 20220365817
    Abstract: Existing techniques of managing Electronic Design Automation (EDA) on cloud are based on pre-defined policies which result in costly burst patterns and server farm tilt. Embodiments of present disclosure overcomes these drawbacks by a method and system for managing EDA on cloud which employ machine learning to predict optimal resource configurations for deploying EDA jobs and configuration circuit on cloud that holds resources required by the optimal resource configuration. Further, different Cloud Service Providers (CSP) are evaluated to determine least cost CSP which has the desired configuration circuit. Completion time of jobs and time required to burst the jobs on cloud are calculated based on which a wait time is determined. The jobs are retained in the queue for corresponding wait time before deploying them on the cloud. The jobs are deployed on the on-prem infrastructure if resources are freed up before the wait time.
