The SD Association recently announced it has defined a new, dual-row pin memory card design achieving bus interface speeds of up to 300 megabytes per second for SDXC and SDHC devices and memory cards. It is fully backwards compatible, allowing equipped devices full use of any SD, SDHC and SDXC memory 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.
“Our innovative dual-row pin design ultimately lets consumers using equipped products to manage the massive storage capacity found on SDXC memory cards at incredible speeds,” said Norm Frentz, chairman of the SD Association. “SD can now support high definition video from Hollywood movie studios, television broadcasts, or HD videos taken on your latest vacation. SD is a very popular, extremely portable and easy-to-use storage medium that has enhanced the enjoyment and portability of music, photos and data. The Association remains committed to helping consumers maintain the value, usefulness and longevity of all of their SD products.”
The Association has created two videos showing optimized uses for the variety of SD memory cards available now here. It also offers an online resource, www.sdcard.org/cardchoice, for users to explore the variety of SD memory cards types for new and existing devices.
