The 256GB version was reported to offer sequential read performance up to 530 MB/s and sequential write performance up to 170 MB/s and random performance of 40,000 read IOPS and 35,000 write IOPS. The cards were based on the UFS 1.0 Card Extension Standard. On 7 July 2016, Samsung announced its first UFS cards, in 32, 64, 128, and 256 GB storage capacities. In April 2015, Samsung's Galaxy S6 family was the first phone to ship with eUFS storage using the UFS 2.0 standard. In February 2013, semiconductor company Toshiba Memory (now Kioxia) started shipping samples of a 64GB NAND flash chip, the first chip to support the then new UFS standard. In 2022 Samsung announced version 4.0 doubling from 11.6 Gbit/s to 23.2 Gbit/s with the use of MIPI M-PHY v5.0 and UniPro v2.0. The Host Performance Booster feature is optional. UFS 3.1 introduces Write Booster, Deep Sleep, Performance Throttling Notification and Host Performance Booster for faster, more power efficient and cheaper UFS solutions. On 30 January 2020 JEDEC published version 3.1 of the UFS standard. At the MWC 2018, Samsung unveiled embedded UFS (eUFS) v3.0 and uMCP (UFS-based multi-chip package) solutions. On 30 January 2018 JEDEC published version 3.0 of the UFS standard, with a higher 11.6 Gbit/s data rate per lane (1450 MB/s) with the use of MIPI M-PHY v4.1 and UniProSM v1.8. JESD220B Universal Flash Storage v2.0 offers increased link bandwidth for performance improvement, a security features extension and additional power saving features over the UFS v1.1. In September 2013, JEDEC published JESD220B UFS 2.0 (update to UFS v1.1 standard published in June 2012). In 2010, the Universal Flash Storage Association (UFSA) was founded as an open trade association to promote the UFS standard. The standard is developed by, and available from, the JEDEC Solid State Technology Association. Unlike eMMC, Universal Flash Storage is based on the SCSI architectural model and supports SCSI Tagged Command Queuing. UFS implements a full-duplex serial LVDS interface that scales better to higher bandwidths than the 8-lane parallel and half-duplex interface of eMMCs. The electrical interface for UFS uses the M-PHY, developed by the MIPI Alliance, a high-speed serial interface targeting 2.9 Gbit/s per lane with up-scalability to 5.8 Gbit/s per lane. UFS is positioned as a replacement for eMMCs and SD cards. The proposed flash memory specification is supported by consumer electronics companies such as Nokia, Sony Ericsson, Texas Instruments, STMicroelectronics, Samsung, Micron, and SK Hynix. It may use multiple stacked 3D TLC NAND flash dies (integrated circuits) with an integrated controller. The standard encompasses both packages permanently attached (embedded) within a device ( eUFS), and removable UFS memory cards. It was designed to bring higher data transfer speed and increased reliability to flash memory storage, while reducing market confusion and removing the need for different adapters for different types of cards. Universal Flash Storage ( UFS) is a flash storage specification for digital cameras, mobile phones and consumer electronic devices. Not to be confused with the Unix File System, a file system implementation in some Unix and BSD operating systems with the same abbreviation. ![]()
