Abstract
A memory system includes a memory controller, a physical layer (PHY), and a memory (e.g., DRAM). Data is written to and read from the memory in different manners for different memory technologies, such as using different signals or signal timings for different memory technologies. Various runtime services specific to the memory technology are performed by the PHY rather than the memory controller. Examples of such runtime services include performing a training routine to train or re-train an interface between the PHY and the memory, performing a power management routine (e.g., to put the main memory in a self-refresh mode), and so forth.
