Abstract
Aspects of the disclosure are directed to providing a single data rate (SDR) mode or a double data rate (DDR) mode to a Registering Clock Drive (RCD) for a memory. Accordingly, the apparatus and method may include determining data rate mode selection criteria; selecting a data rate mode based on the data rate mode selection criteria; configuring a host interface for the data rate mode; and configuring an RCD input interface for the data rate mode. In one aspect, the apparatus and method further include activating a clock signal on the host interface and on the RCD input interface; transferring data from the host interface to the RCD input interface using the clock signal; and transferring the data from an RCD output interface using the clock signal in either 1N mode or 2N mode. And, the data rate mode is one of the SDR mode or the DDR mode.
