Universal Flash Storage (UFS) is an advanced, high performance interface designed for computing and mobile systems such as smartphones and tablets where power consumption needs to be minimal. The major differences between UFS/UFS Card over the older signaling architecture based eMMC/SD cards are its high speeds and low power serial interface with high reliability. In light of the UFS’s high performance and reliability, Samsung has seen adoption in the mobile market. Samsung will continue to satisfy the growing storage needs of the industry by offering a variety of advanced UFS lineups, while more thoroughly addressing the ever-increasing demand for leading-edge memory solutions in other market segments, too. UFS – An Ultra-Fast Embedded Storage Solution to Replace eMMC UFS improves read and write performance of flash memory in two ways. First, unlike eMMC, there are dedicated channels for reading and writing data allowing for simultaneous read/write data flow. The second advantage of UFS is Command Queuing. This is the efficient grouping and (re)ordering of read or write commands to maximize the performance throughput.

UFS Card – A Memory Card up to 70 Times Faster than SD Cards The Samsung UFS Card is specifically designed for advanced applications that require fast and large external storage for content such as 4K/8K video recording, 360-degree VR, RAW images and high-end mobile devices. The UFS Card has a similar form factor to the standard microSD (11x15mm) and is designed so that both UFS Card and microSD cards can be used in a single combo socket.

uMCP- A One-Chip Solution Embedding UFS and DRAM As mentioned previously, UFS is replacing eMMC with its superior performance and lower power consumption than eMMC, so the industry is demanding a one chip solution with UFS technology. The Samsung flagship GX128.48 uMCP is among the highest capacities available and unifies DRAM and NAND flash technology into a single low-profile, small-form-factor package while incorporating 128 GB of UFS-based fourth-generation NAND flash storage and 6 GB LPDDR4X DRAM. The following are performance comparisons between uMCP and eMCP for three UX scenarios.
