An apparatus includes: a first memory controller that corresponds with a first type of non-volatile memory device; a second memory controller that corresponds to a second type of non-volatile memory device, wherein the second type of non-volatile memory device is different from the first type of non-volatile memory device; an physical layer (PHY) interface; and an interface controller coupled to the PHY interface for controlling signal transmission by the PHY interface; wherein the PHY interface is selectively configurable or is user-configured to allow the PHY interface to communicate with one or more memory devices belonging to the first type, the second type, or both.
