JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of JESD220-2 Universal Flash Storage (UFS) Card Extension Standard. The new removable memory card standard standardizes functionality that aligns with the popular UFS embedded device standard. JESD220-2 is available for free download from the JEDEC website.UFS is a high performance interface designed for use in computing and mobile systems such as smart phones and tablets where power consumption needs to be minimized. Its high speed serial interface and optimized protocol enable significant improvements in throughput and mobile system performance. The new UFS card standard provides a leading-edge removable storage solution while maintaining sequential and random IOPS performance that is critical for future mobile markets. Even using a single lane the UFS 1.0 card offers 600 MB/s interface speed in both directions and a state-of-the-art queuing mechanism to further increase system throughput.Features of the UFS card are the same as those defined in the UFS 2.0 embedded device standard:To optimize for cost, complexity, and assist with rapid implementation of the new UFS 1.0 card standard, product designers and engineers should note the following key areas of simplification from the embedded UFS 2.0 standard:"JEDEC's new UFS card standard offers many of the features and much of the same high-end functionality as the UFS embedded device standard, but in a convenient, removable card format that would be well suited for most mobile devices," said Mian Quddus, Chairman of the JEDEC Board of Directors and the JC-64 Committee for Embedded Memory Storage and Removable Memory Cards. He added, "JC-64 is dedicated to fulfilling the storage requirements of the mobile industry by offering product designers a range of options to better meet their needs."Samsung: "Embedded UFS has been proven to deliver the best performance and highest power efficiency of any storage in the mobile industry," said Kenny Han, vice president, NAND product planning, Samsung Electronics. "It is only natural that this exemplary performance is being passed on to removable cards in extending the functionality of consumer mobile devices. The new UFS card standard will more than meet the needs of technologies that are the vanguard of the mobile industry today like 360-degree video and Drones with multiple 4K/8K recording cameras as well as smartphones which are beginning to evolve into intelligent hubs for IoT and mobile environments."For more information, visit this page
