Patent number: 11682437Abstract: A system includes a mixer of a phase interpolator. The mixer includes a dynamic load whose output signal is coupled to a subsequent stage of the phase interpolator. The dynamic load is configured to provide an alternating current (AC) signal to the subsequent stage of the phase interpolator as input clock signals. The mixer further includes a static load whose output signal is coupled to the subsequent stage of the phase interpolator in parallel with the respective output signal line of the dynamic load. The static load configured to provide a direct current (DC) signal to the phase interpolator temporarily in replacement of the respective AC signals to prevent output signals of the subsequent stage of the phase interpolator from being unpredictable.Type: GrantFiled: August 31, 2021Date of Patent: June 20, 2023Assignee: Micron Technology, Inc.Inventors: Steven G. Wurzer, Jeremy Kuehlwein, Michael J. O'Brien

Patent number: 10840924Abstract: Apparatuses and methods for phase interpolators are provided. An example apparatus comprises a phase interpolator and a controller coupled to the phase interpolator. The controller is configured to provide a digital timing code to the phase interpolator, and the phase interpolator is configured to apply a correction to the received digital timing code based, at least in part, on phase interpolator error correction data from a data structure containing phase interpolator error correction data.Type: GrantFiled: August 7, 2019Date of Patent: November 17, 2020Assignee: Micron Technology, Inc.Inventors: Steven G. Wurzer, Neil Petrie, Joseph P. Kerzman, Kevin R. Duncan

Patent number: 10680795Abstract: Apparatuses and methods for quadrature signal generation are provided. An example includes a quadrature signal generator. The quadrature signal generator is configured to generate, based on a received differential signal, a plurality of quadrature clock signals at a same frequency as that of the received differential signal. The quadrature signal generator is also configured to provide the plurality of quadrature clock signals to a memory system.Type: GrantFiled: May 29, 2019Date of Patent: June 9, 2020Assignee: Micron Technology, Inc.Inventors: Liuchun Cai, Steven G. Wurzer, Gregory A. King
