  • Patent number: 11948661
    Abstract: Memory devices, systems including memory devices, and methods of operating memory devices are described, in which clock trees can be separately optimized to provide a coarse alignment between a clock signal and a command/address signal (and/or a chip select signal or other control signal), and/or in which individual memory devices can be isolated for fine-tuning of device-specific alignment between a clock signal and a command/address signal (and/or a chip select signal or other control signal). Moreover, individual memory devices can be isolated for fine-tuning of device-specific equalization of a command/address signal (and/or a chip select signal or other control signal).

  • Patent number: 11830578
    Abstract: Methods, systems, and apparatuses for managing clock signals at a memory device are described. A memory device or other component of a memory module or electronic system may offset a received clock signal. For example, the memory device may receive a clock signal that has a nominal speed or frequency of operation for a system, and the memory device may adjust or offset the clock signal based on other operating factors, such as the speed or frequency of other signals, physical constraints, indications received from a host device, or the like. A clock offset value may be based on propagation of, for example, command/address signaling. In some examples, a memory module may include a registering clock driver (RCD), hub, or local controller that may manage or coordinate clock offsets among or between various memory devices on the module. Clock offset values may be programmed to a mode register or registers.
