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. At the MWC 2018, Samsung unveiled embedded UFS (eUFS) v3.0 and uMCP (UFS-based multi-chip package ) solutions.
On January 30, 2018, JEDEC published the UFS 3.0 standard which uses MIPI M-PHY v4.1 (with HS-Gear4) and MIPI UniPro v1.8 for mobile memory with data rates up to 2900 MB/s (11,6 Gbit/s per lane, 2 lanes, 23,2 Gbit/s total).
JEDEC is an organization devoted to standards for the solid-state industry. The latest eMMC specifications can be requested from JEDEC, free-of-charge for JEDEC members. [ 7 ] Older versions of the standard are freely available, but some optional enhancements to the standard such as MiCard and SecureMMC specifications, must be purchased separately.
A Replay Protected Memory Block (RPMB) is provided as a means for a system to store data to the specific memory area in an authenticated and replay protected manner and can only be read and written via successfully authenticated read and write accesses.
The only thing being given undue weight in this is the IEC units. Unlike those, the JEDEC units are actually used in marketing, documentation, reviews and packaging for memory-related products. —Locke Cole • t • c 16:09, 5 May 2021 (UTC) For reasons not clear to me this issue appears to be very sensitive.
Some UFS implementations avoid journaling and instead implement soft updates: they order their writes in such a way that the on-disk file system is never inconsistent, or that the only inconsistency that can be created in the event of a crash is a storage leak. To recover from these leaks, the free space map is reconciled against a full walk of ...
Support was added at the block device layer in 8.1. Filesystem support was added in FreeBSD 8.3 and FreeBSD 9, beginning with UFS. [18] ZFS trimming support was added in FreeBSD 9.2. [19] [20] FreeBSD 10 supports trimming on software RAID configurations. [21] NetBSD: October 2012 [22] Linux: 2.6.28–25 December 2008 [23]
Also in 2008, JMicron showcased a number of peripheral products. This includes the JMB353, a hi-speed USB & IEEE 1394a to SATA II external HDD controller chip; this device was the first to feature an integrated IEEE 1394a PHY chip.
