Patent number: 10082823Abstract: An apparatus comprising an open loop circuit and a delay circuit. The open loop circuit may be configured to generate an in-phase clock signal by performing a phase alignment in response to (i) a clean version of a system clock and (ii) a delayed version of a strobe signal. The delay circuit may be configured to (i) generate the delayed version of the strobe signal in response to (a) the strobe signal received from a memory interface and (b) a delay amount received from a calibration circuit and (ii) adjust a delay of transferring a data signal through the apparatus in response to (a) the delay amount and (b) the in-phase clock signal. The data signal may be received from the memory interface. The delay of transferring the data signal may be implemented to keep a latency of a data transfer within a pre-defined range.Type: GrantFiled: October 11, 2017Date of Patent: September 25, 2018Assignee: INTEGRATED DEVICE TECHNOLOGY, INC.Inventors: David Chang, Xudong Shi

Patent number: 10078456Abstract: Techniques are disclosed relating to resolving memory access hazards. In one embodiment, an apparatus includes a memory and circuitry coupled to or comprised in the memory. In this embodiment, the circuitry is configured to receive a sequence of memory access requests for the memory, where the sequence of memory access requests is configured to access locations associated with entries in a matrix. In this embodiment, the circuitry is configured with memory access constraints for the sequence of memory access requests. In this embodiment, the circuitry is configured to grant the sequence of memory access requests subject to the memory access constraints, thereby avoiding memory access hazards for a sequence of memory accesses corresponding to the sequence of memory access requests.Type: GrantFiled: October 24, 2014Date of Patent: September 18, 2018Assignee: NATIONAL INSTRUMENTS CORPORATIONInventors: Tai A. Ly, Swapnil D. Mhaske, Hojin Kee, Adam T. Arnesen, David C. Uliana, Newton G. Petersen

Patent number: 10073833Abstract: Large lists of domain-specific terms are classified as a particular kind of linguistic object, e.g., lexical answer type T versus canonical answer E, based on features from a domain-specific corpus which have been found to distinguish between the linguistic objects. The distinguishing features can be identified in the corpus based on sets of the linguistic objects derived from question-and-answer pairs. A classifier can be trained using the distinguishing features, and the classification carried out using that classifier. The distinguishing features can include one or more syntactic features or one or more lexical features. The linguistic objects (the T and E training sets) can be extracted from the question-and-answer pairs automatically via text analysis if manually curated lists are not available. The classified terms can be included in a domain-specific lexicon which facilitates a deep question answering system to yield an answer to a question.Type: GrantFiled: June 9, 2017Date of Patent: September 11, 2018Assignee: International Business Machines CorporationInventors: Charles E. Beller, Paul J. Chase, Jr., Richard L. Darden, Michael Drzewucki, Edward G. Katz, Christopher Phipps, James E. Ramirez

Patent number: 10031907Abstract: An aspect of auto-completion of text entered by a user includes configurable data collection components that collect from software applications text data and metadata representing an initial state of each of the applications and text data and metadata representing changes to the state of one or more of the applications. A central text matching component receives and stores the text data and metadata. A sending component sends text entered by the user in a text-entry field and any metadata associated with it to the central text matching component. A comparison component compares the entered text and associated metadata to the stored text data and metadata and locates matching text strings. A weighted ordering component ranks the matching text strings using the metadata and its configuration settings. A completion component completes the entered text at the text-entry field based on a selection of one of the located matching text strings.Type: GrantFiled: July 22, 2015Date of Patent: July 24, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: David R.

Patent number: 9966147Abstract: Systems and methods presented herein provide for computing read voltages for a storage device. In one embodiment, a controller is controller is operable to soft read data from a portion of the storage device, and to iteratively test the soft read data a predetermined number of times. For example, the controller may test the soft read data a number of times by applying a different probability weight to the soft read data each time the soft read data is tested. The controller may then decode the soft read data based on the probability weight, and determine an error metric of the decoded soft read data. Then, the controller determines a read voltage for the portion of the storage device based on the probability weight and the error metric.Type: GrantFiled: August 14, 2017Date of Patent: May 8, 2018Assignee: Seagate TechnologyInventors: Nicholas Odin Lien, Ryan James Goss
