The Universal Flash Storage Association (UFSA) expects the UFS to become the dominant mobile storage interface within just three years, with numerous designs enter 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 added.
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 improvements in throughput and system performance.
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 proven set of commands that improves system performance.
The Universal Flash Storage Association (UFSA) was founded in 2010 as an open trade association to promote 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.
