At present, eMMC/eMCP is the mainstream storage solution for smartphones and tablet computers. EMMC integrates the main controller and NAND Flash particles into a small BGA package, which effectively solves the problem of NAND Flash management. With the development of the market and the advancement of technology, the speed is also increasing: eMMC 4.41 104MB/s, eMMC 4.5 200MB/s, eMMC 5.0 400MB/s, and the next generation specifications will be followed by UFS 2.0.
The conversion of an embedded storage specification to a UFS is similar to the conversion of an SSD SATAIII interface to a PCIe interface. It supports full-duplex running, simultaneous read and writes operations, more efficient power management during operations, and instruction queuing. In contrast, eMMC is half-duplex, where reads and writes must be executed separately, and instructions are packaged.
There are two versions of UFS 2.0, each with two transmission channels. The theoretical bandwidth of HS-G2 is 5.8Gbps, which is more than 740MB/s, while that of HS-G3 is doubled to 11.6Gbps, which is close to 1.5GB/s, which is enough to meet the needs of the future for a long time, and 4K video recording and playback will be more smooth.
