SD Association reveals new Memory Card Design for fast Cards

New high speed interface signals will be assigned on the second row of pins of select SDXC and SDHC memory cards offering the new speed. This option will be available in both full-size and micro form factors and does not change the physical size or shape of the cards. This design will be part of the forthcoming SD 4.0 specification, expected in early 2011.

At IFA, the Association is displaying new and exciting products based on SDXC, its latest standard. Attendees can see more than 40 products from 18 different global brands including memory cards, HD digital cameras, HD video cameras, HD televisions, e-books, card readers, controllers and developer kits.

Several of the products on display feature the recently announced Ultra High Speed (UHS) UHS-I and UHS Speed Class high-speed capabilities. UHS-I technology is found exclusively on SDXC and SDHC products. It offers faster bus-interface speeds, with data transfer speeds up to 104 megabytes per second. The new UHS Speed Class 1 technology offers a performance option designed to support real-time video recording. Consumers can realize the full potential of these technologies by pairing their devices and memory cards.
