JEDEC Solid State Technology Association Debuts JESD220B UFS v2.0

JEDEC Solid State Technology Association published version two of the Universal Flash Storage standard. JESD220B UFS v2.0 features increased link bandwidth for performance improvement, a security features extension, and additional power saving features over the prior version. Universal Flash Storage v2.0 may be downloaded free of charge.

Universal Flash Storage (UFS) version 2.0 was developed for mobile applications and computing systems requiring high performance and low power consumption. UFS v2.0 offers significant performance improvements that will lead to a better overall mobile device user experience. UFS 2.0 will drive next generation mobile devices to new performance levels not available before.

To achieve the highest performance and most power efficient data transport, JEDEC UFS aligns with industry–leading specifications from the MIPI Alliance to form its Interconnect Layer. This collaboration continues with UFS v2.0, which references the M-PHY Version 3.0 specification and the UniPro Version 1.6 specification.

UFS is a high performance interface designed for use in computing and mobile systems requiring low power consumption such as smart phones and tablets. Its high speed serial interface and optimized protocol enable significant improvements in throughput and system performance. UFS v2.0 builds on JEDEC Flash memory storage standards designed to help address this demand. In UFS v2.0, the link bandwidth has been increased from 300 MB/s in UFS v1.1 to up to 600 MB/s per lane, and multi-lane support has been introduced allowing up to 1.2 GB/s per each data transfer direction.
