Publication number: 20200118608Abstract: Apparatuses and methods for providing voltages to conductive lines between which clock signal lines are disposed are disclosed. Voltages provided to the conductive lines may provide voltage conditions for clock signals on the clock signal lines that are relatively the same for at least some of the clock edges of the clock signals. Having the same voltage conditions may mitigate variations in timing/phase between the clock signals due to different voltage influences when a clock signal transitions from a low clock level to a high clock level.Type: ApplicationFiled: June 10, 2019Publication date: April 16, 2020Applicant: MICRON TECHNOLOGY, INC.Inventors: Katsuhiro Kitagawa, Akira Yamashita, Shuichi Murai, Kohei Nakamura
