  • Publication number: 20210365205
    Abstract: The present disclosure includes systems, apparatuses and methods related to maintaining data in a sorted order in a memory array to improve access time to data in the memory array and directing access to a row of data in cache based upon an address associated with the data. In a number of embodiments, a number of keys that are stored in a first row of an index table can be split between the first row and a second row in response to the first row being full, where the number of keys are copied to the second row and a first portion of the number of keys remain in the first row and a second portion of the number of keys are moved to the second row.

  • Publication number: 20210365360
    Abstract: Methods, apparatuses, and systems related to mapping a virtual address using a content addressable memory (CAM) are described. In a memory system including a memory and a content addressable memory (CAM), a select line of the CAM can be coupled to a corresponding select line of the memory, which allows the memory system to map a virtual address of a memory device directly to the corresponding select line of the memory. An example method can include receiving, from a host at a memory device comprising a memory array and a content addressable memory (CAM), a first virtual address to be searched among virtual addresses stored within the CAM, identifying, in response to receipt of the first virtual address, a select line of a plurality of select lines of the CAM associated with a second virtual address matching the first virtual address, and activating, in response to identifying the select line of the CAM, a corresponding select line of the memory coupled to the identified select line of the CAM.

  • Publication number: 20210365383
    Abstract: Apparatuses, systems, and methods for mapping a virtual address using a CAM are described. A parallel structure of a CAM can enable functions of a MMU to be integrated into a single operation performed using the CAM such that a virtual address of a memory array can be mapped directly to a row of a memory. An example method includes receiving an access command and address information for a memory array; identifying a virtual address and a physical address of the memory array based on the received address information; comparing, during a time period associated with the access command, the virtual address and the physical address to virtual addresses and physical addresses, respectively, of the memory array stored in a CAM; and accessing, during the time period, a row of the memory array coupled to a row of the CAM storing the virtual address and the physical address.

  • Publication number: 20210313143
    Abstract: Methods for exposing a desired shape in an area on a surface using a charged particle beam system include determining a local pattern density for the area of the desired shape based on an original set of exposure information. A backscatter for a sub area is calculated, based on the original set of exposure information. Dosage for at least one pixel in a plurality of pixels in the sub area is increased, in a location where the backscatter of the sub area is below a pre-determined threshold, thereby increasing the backscatter of the sub area. A pre-PEC maximum dose is determined for the local pattern density, based on a pre-determined target post-PEC maximum dose. The original set of exposure information is modified with the pre-PEC maximum dose and the increased dosage of the at least one pixel in the sub area to create a modified set of exposure information.

  • Patent number: 11126085
    Abstract: Methods include inputting an array of pixels, where each pixel in the array of pixels has a pixel dose. The array of pixels represents dosage on a surface to be exposed with a plurality of patterns, each pattern of the plurality of patterns having an edge. A target bias is input. An edge of a pattern in the plurality of patterns is identified. For each pixel which is in a neighborhood of the identified edge, a calculated pixel dose is calculated such that the identified edge is relocated by the target bias. The array of pixels with the calculated pixel doses is output. Systems for performing the methods are also disclosed.

  • Patent number: 10731630
    Abstract: A control method for increasing reactive power generation of a wind turbine having a Doubly-Fed Induction Generator (DFIG) includes obtaining, by a control device having one or more processors and one or more memory devices, wind forecast data of the wind turbine. Further, the method includes generating, by the control device, a real-time thermal model of the DFIG of the wind turbine using the wind forecast data. More specifically, the thermal model defines a thermal capacity for the DFIG that does not exceed system limits. Thus, the method also includes dynamically adjusting, by the control device, a reactive power set point of the DFIG of the wind turbine based on the real-time thermal model.
