Universal Flash Storage (UFS) is a common flash storage specification for digital cameras, mobile phones and consumer electronic devices.〔(JEDEC Announces Publication of Universal Flash Storage (UFS) Standard )〕 This could bring higher data transfer speed and increased reliability in flash memory storage, thus reducing market confusion and the varying number of adapters for different number of cards. The proposed specification is supported by leading firms in the consumer electronics industry such as Nokia, Sony Ericsson, Texas Instruments, STMicroelectronics, Samsung, Micron, SK Hynix. UFS is positioned as a replacement for eMMCs and SD cards. The electrical interface for UFS uses the M-PHY,〔http://www.mipi.org/about-mipi/industry-associations/jedec-solid-state-technology-association/〕 developed by the MIPI Alliance, a high speed serial interface targeting 2.9 Gbps (gigabits per second) per lane with up-scalability to 5.8 Gbps per lane.〔http://www.mipi.org/〕〔http://toshiba.semicon-storage.com/eu/application/ufs.html〕 UFS implements a full-duplex serial LVDS SATA interface that scales better to higher bandwidths than the 8-lane parallel interface of eMMCs. Unlike eMMC, Universal Flash Storage is based on the SCSI architectural model and supports Native Command Queuing.〔http://global.samsungtomorrow.com/emmc-to-ufs-how-nand-memory-for-mobile-products-is-evolving/〕〔http://www.design-reuse.com/articles/30845/universal-flash-storage-mobilize-your-data.html〕 The standard is developed by, and available from, the JEDEC Solid State Technology Association. In September 2013, JEDEC published JESD220B UFS 2.0 (update to UFS v1.1 standard published in June 2012). 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.〔http://www.jedec.org/standards-documents/focus/flash/universal-flash-storage-ufs〕 The Linux kernel supports UFS.〔https://www.kernel.org/doc/Documentation/scsi/ufs.txt〕 ==See also== * Memory Card * Solid-state drive * Flash Memory * JEDEC * Secure USB drive 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Universal Flash Storage」の詳細全文を読む スポンサード リンク
