AUSTIN, Texas -- February 26, 2014

The Universal Flash Storage (UFS) version 2.0 standard, supported by the
mobile industry and published in late 2013 by JEDEC, is projected to
experience wide market adoption more quickly than previous storage offerings.
UFS v2.0 bandwidth supports up to a 1.2 GB/s data transfer rate using a
multi-lane approach, which is three times greater than that of the fastest
flash storage chip today – eMMC 5.0.

UFS is projected to be the dominant mobile storage interface within just three
years, with numerous designs expected to be in production in 2014 and 2015.

"UFS will bring substantial added performance and design flexibility to the
next generation of mobile platform development, beginning in the second
quarter," said UFSA (Universal Flash Storage Association) President Lisa
Rhoden. "Moreover, UFS's wide-ranging set of improvements to the mobile
storage space will provide a markedly improved experience for consumers," she

“UFS is a major step forward in storage for next generation mobile systems and
is expected to proliferate rapidly to mainstream mobile applications and
beyond over the next few years,” said Forward Insights President, Gregory
Wong. “UFS enables designers to dramatically improve system performance
thereby enhancing the user experience of mobile devices.”

UFS is a high performance, scalable storage interface designed for use in
computing and mobile systems requiring low power consumption. Its high speed
serial interface and optimized protocol enable significant improvements in
throughput and system performance. Dramatic growth in the mobile market
coupled with an increasing market focus on multimedia applications continues
to drive usage and memory bandwidth requirements. The new UFS v2.0 sharply
improves upon existing JEDEC Flash memory storage standards to help address
this demand.

UFS provides benefits not supported by other mobile storage interfaces. Using
MIPI M-PHY as the physical layer allows scalability and variability in data
rate, signal count and power requirements with multiple-lane support options
in a full-duplex serial implementation. Command queuing, concurrent
operations, increased IOPS and reduced read/write latencies provide additional
performance improvements and security features that enhance multimedia
transfer in mobile devices.

The JEDEC UFS v2.0 standard utilizes MIPI M-PHY v3.0 and MIPI UniPro v1.6
specifications as its building blocks. MIPI M-PHY is a serial interface with
high bandwidth capabilities, specifically developed for mobile applications to
obtain a low signal count combined with excellent power efficiency. It is
targeted for use with multiple protocols, including UniPro ─ a layered
protocol for interconnecting devices and components within mobile device
systems, and UFS as the application layer. This integration is a result of
close collaboration between JEDEC and the MIPI alliance, which has brought the
benefits of these specifications to the mobile storage space.

JEDEC UFS v2.0 incorporates the INCITS T10 (SCSI) command set to provide a
rich, powerful and proven set of commands that improves system performance.
UFS improves OS responsiveness and enables a richer user experience when
storing or playing multimedia files, in addition to providing greater power
efficiency. UFS also enables more secure mobile platforms, which further
encourages innovation in systems and applications.

About UFSA

The Universal Flash Storage Association (UFSA) was founded in 2010 as an open
trade association to promote widespread adoption and acceptance of the UFS
standard. Board of Director members include Agilent Technologies, Micron
Technology, Phison Electronics, Samsung Electronics, Silicon Motion Technology
and SK Hynix. For more information about UFSA: http://www.universalflash.org/

Sample support quotes from member companies

“We’ve seen an exponential growth of interest and an increase in the number of
licensees of our UFS IP product portfolio during the latter half of 2013. UFS
2.0 with MPHY at Gear 3 speeds have given UFS a huge advantage in speed and
power over competing standards. We expect this demand to accelerate during
this year as UFS gains broader market acceptance beyond mobile. Arasan is
geared to meet this increased demand,” said Zachi Friedman, Director of
Marketing, Arasan Chip Systems, Inc.

“With more functionality being incorporated into mobile SoC designs, Synopsys
is seeing significant demand for IP interfaces such as JEDEC UFS,” said John
Koeter, vice president of marketing for IP and systems at Synopsys. “As the
JEDEC UFS 2.0 standard gains widespread adoption in low-power mobile
applications, SoC designers can continue to rely on Synopsys to provide
silicon-proven mobile storage UFS and MIPI IP solutions that meet their low
power, low latency, and compact footprint requirements.”
