CONFIGURING MULTIPLE REGISTER CLOCK DRIVERS OF A MEMORY SUBSYSTEM

Methods, systems, and apparatuses related to configured dual register clock driver (RCD) devices on a single memory subsystem using different configuration information are described. In some examples, configuration of the two RCD devices with different configuration information may include use of a serial data bus to receive and store first RCD configuration data, which is provided to both of the RCD devices to configure one or more parameters of each respective RCD device. One of the RCD devices may receive second configuration data via a command and address bus to independently update the one or more configuration parameters of one of the two RCD devices.
