This standard specifies the characteristics of the UFS electrical interface and the memory device. Such characteristics include (among others) low power consumption, high data throughput, low electromagnetic interference and optimization for mass memory subsystem efficiency. The UFS electrical interface is based on an advanced differential interface by MIPI M-PHY standard which together with the MIPI UniPro standard forms the interconnect of the UFS interface. The architectural model is referencing the INCITS T10 SAM standard and the command protocol is based on INCITS T10 (SCSI) SPC and SBC standards.

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. The following is the summary of the UFS features.
