Samsung Develops Tiny 1-Gbyte Memory Card--World's Fastest

Designed for cell phones, digital cameras, and MP3 players, the card writes at 7.12 Mbytes per second, 3.5 times as fast as other micro cards.
SEOUL, South Korea — Samsung Electronics Co. Ltd. has developed a micro memory card, designated 1GB MMCmicro, with a 1-Gbyte density and reportedly the fastest writing and reading speed.

Designed for cellphones, digital cameras and MP3 players, the card writes at 7.12 megabytes per second, 3.5 times as fast as other micro cards. It reads at 7.38 megabytes per second, compared with 7.10 megabytes per second for existing products, Samsung reported.

"The card is large enough to store 15 hours of mobile video and fast enough to download 90 minutes of video in less than two minutes," said Don Barnetson, associate director of flash marketing, Samsung Semiconductor USA.

The card operates on 1.8 or 3.3 volts, with the lower voltage version consuming 82 percent less power than other micro-size cards, said Samsung. An adapter allows the card to plug into any multimedia card slot.

Housing four NAND flash memories and a controller, the card measures 12 x 14 x 1.1 mm. It will be available the third quarter.

Semiconductor research firm Dataquest expects the global market for micro memory cards to grow at an 81 percent compound annual growth rate between 2005 and 2010, from 4 million to 77 million units.
