UFS will provide a dramatic change in architecture to increase performance while maintaining the benefits of low power consumption offered by existing solutions such as eMMC. The new standard will be based on a high speed serial interface targeting up to 2.9 gigabits per second (Gbps) with up-scalability to 5.8Gbps. UFS will initially offer three times the interface speed of the prevalent e�MMC interface, which is comparable to serial ATA-2. Moreover, UFS will offer the promise for significant reductions in device power consumption due to a low active power level and a near-zero idle power level.
The new standard also will support multiple commands with command queuing features and enabling a multi-thread programming paradigm, unlike conventional flash-based memory cards and embedded flash solutions such as eMMC, which process one command at a time, limiting random read/write access performance.
Speaking from a recent technical committee meeting in San Francisco, Mian Quddus, Chairman of JEDEC's JC-64 Committee for Flash Memory Modules, noted: "UFS as an industry-wide flash storage standard will address a number of market demands, including faster data access, lower power consumption, and improved performance for flash-based devices, benefiting device designers and consumers alike."
JEDEC will offer an overview of UFS at its 2011 International CES conference program.
