  • Publication number: 20240211151
    Abstract: An apparatus for performing a write data strobe concurrent with a reference voltage calibration is disclosed. A memory controller circuit is configured to convey a write clock signal to a memory. The memory controller circuit includes a calibration circuit configured to send a first command to memory to initiate a calibration of the write clock signal and, after an amount of time has elapsed, receive a calibration value from the memory. The memory controller further includes a delay circuit configured to apply a delay to the write clock signal, wherein the calibration circuit is configured to complete calibration of the write clock signal by adjusting the delay applied to the write clock signal in accordance with the calibration value. The calibration circuit is further configured to perform a reference voltage calibration concurrent with the calibration of the write clock signal.

  • Patent number: 11960739
    Abstract: The present disclosure is directed to a reference voltage calibration. An apparatus includes a memory and a memory controller including a calibration circuit configured to perform a reference voltage calibration to determine a reference voltage used to distinguish between logic values read from the memory. The reference voltage calibration comprises performing horizontal calibrations at different reference voltage values to determine a range of delay values applied to a data strobe signal at which valid data is read from the memory. The calibration includes determining scores corresponding to ones of the plurality of horizontal calibrations in which a score for a particular one of the plurality of horizontal calibrations is based on a corresponding range of delay values and a reference voltage margin. Thereafter, the calibration circuit selects a calibrated reference voltage based on the scores corresponding to ones of the plurality of horizontal calibrations.

  • Publication number: 20240058066
    Abstract: A surgical planning system may be configured to predict a relationship between two or more bones, including adjoining and/or non-adjoining bones of a patient. The system may be configured to select a representative bone model associated with a bone in response to comparing the representative bone model to a patient bone model associated with the bone of a patient. The system may be configured to determine at least one patient characteristic based on a relationship of the representative and/or patient bone model to another bone model, which may be associated with an adjoining or non-adjoining bone. A method of planning a surgical procedure is also disclosed.

  • Publication number: 20230097140
    Abstract: This disclosure relates to planning systems, methods and instrumentation. The planning systems, methods and instrumentation disclosed herein may be utilized for planning orthopaedic procedures to restore functionality to a joint, may include determining an amount of bone loss along or otherwise adjacent to an articular surface of a bone. Instrumentation may be formed based on one or more dimensions associated with the bone loss. The articular surface may be repaired, which may include utilizing the instrumentation and planning systems to position and secure a bone graft along a position of the bone associated with the bone loss.
