Abstract
Systems and method are directed to a Universal Flash Storage (UFS) host capable of interfacing one or more UFS devices. The UFS host includes a plurality of mobile-physical-layers (M-PHYs) for supporting one or more lanes of traffic between the UFS host and the one or more UFS devices. A Reference M-PHY MODULE Interface (RMMI) router is coupled between a Unified Protocol link layer (Unipro) and the plurality of M-PHYs. The RMMI router is configurable in a transparent mode to pass traffic, without routing, between the UFS host and a 2-lane embedded UFS device through the two M-PHYs. The RMMI router is configurable in a routing mode, to route traffic to a first M-PHY interfacing a 1-lane embedded UFS device or to a second M-PHY interfacing a 1-lane removable UFS card. The RMMI router is configurable based on metal strap or read only memory (ROM) setting.
