JEDEC, one of the most important standard setting organizations in the industry, will describe new memory standards for mobile devices, a critical focus for today’s design engineers, at its forthcoming events. Among other things, JEDEC will talk about LPDDR3, WideIO and UFS (universal flash storage) interfaces.
"Ever-increasing expectations for mobile device performance are driving the need for versatile mobile memory solutions. Attendees will discover how technological advancements and new standards will power applications and have a profound impact on mobile devices now and in the future," said Mian Quddus, the chairman of JEDEC’s board of directors.
The JEDEC LPDDR3 standard is being designed to meet the higher bandwidth requirements of next-generation smartphones and tablets. JEDEC LPDDR3 will offer an extension of LPDDR2, in terms of bandwidth, reaching 6.4GB/s and allowing 12.8GB/s for a dual-channel configuration. It will support both Pop and discrete packaging types, allowing versatile usage. The standard will also preserve the power-efficient features and signaling interface of LPDDR2, allowing for fast clock stop/start, low-power self-refresh, smart array management, and un-terminated signal lanes.
The JEDEC WideIO standard is a technology that will meet industry demands for increased levels of integration as well as improved bandwidth, latency, power, weight and form factor; providing the ultimate in performance, energy efficiency and small size for smartphones, tablets, handheld gaming consoles and other high performance mobile devices. WideIO Mobile DRAM Memory uses chip-level three dimensional (3D) stacking with through silicon via (TSV) interconnects and memory chips directly stacked upon a system-on-chip. WideIO is particularly suited for applications requiring increased memory bandwidth up to 12.8GB/s.
JEDEC published its next-generation storage system standard, universal flash storage (UFS), JESD220 in February 2011. JESD220 may be downloaded free of charge from the JEDEC website. UFS is designed to be a specification for both embedded and removable flash memory-based storage in mobile devices such as smart phones and tablet computers.
