Background of JEDEC UFS:
Universal Flash Storage (UFS) is a simple, high performance, mass storage device with a serial interface. It is primarily for use in mobile systems, between host processing and mass storage memory devices. Potential UFS devices can be memory cards (full size and micro size), embedded bootable mass storage devices, IO devices etc. A UFS device comprises of a device manager, multiple logical units and descriptors. The device manager performs device level functions like power management while the logical unit performs functions like read, write etc. The descriptors are meant for storage of configuration related information.
UFS has to support several SCSI commands, task management commands and interaction with the underlying service delivery mechanism that consists of MIPI UniPro 1.6 and MIPI M-PHY 3.0 .
