  • Patent number: 11876122
    Abstract: A method of forming a semiconductor device. A substrate having a fin structure is provided. A dummy gate is formed on the fin structure. A polymer block is formed adjacent to a corner between the dummy gate and the fin structure. The polymer block is subjected to a nitrogen plasma treatment, thereby forming a nitridation layer in proximity to a sidewall of the dummy gate under the polymer block. After subjecting the polymer block to the nitrogen plasma treatment, a seal layer is formed on the sidewall of the dummy gate and on the polymer block. An epitaxial layer is then grown on a source/drain region of the fin structure. The dummy gate is then replaced with a metal gate.

  • Publication number: 20240004797
    Abstract: Methods and apparatus for efficiently merging non-identical pages in Kernel Same-page Merging (KSM) for efficient and improved memory deduplication and security. The methods and apparatus identify memory pages with similar data and selectively merge those pages based on criteria such as a threshold. Memory pages in memory for a computing platform are scanned to identify pages storing similar but not identical data. A delta record between the similar memory pages is created, and it is determined whether a size of the delta (i.e., amount of content that is different) is less than a threshold. If so, the delta record is used to merge the pages. In one aspect, operations for creating delta records and merging the content of memory pages using delta records is offloaded from a platform's CPU. Support for memory reads and memory writes are provided utilizing delta records, including merging and unmerging pages under applicable conditions.

    Abstract: Technologies for dynamically managing a batch size of packets include a network device. The network device is to receive, into a queue, packets from a remote node to be processed by the network device, determine a throughput provided by the network device while the packets are processed, determine whether the determined throughput satisfies a predefined condition, and adjust a batch size of packets in response to a determination that the determined throughput satisfies a predefined condition. The batch size is indicative of a threshold number of queued packets required to be present in the queue before the queued packets in the queue can be processed by the network device.
