Toshiba announces family of high-speed SD cards
Posted on 13-Jan-2004 20:56 | Tags Filed under: News

The SD Memory Card was originally developed by Toshiba, SanDisk, and Matsushita. Although its encryption capability supports security and content protection applications, its initial usage has been mostly for regular storage due to its small form factor, fast data transfer rate and storage capacities. The card utilizes a 4-bit interface that enables it to have higher performance capabilities, including a faster data transfer rate, compared to the MMC, which employs a 1-bit interface.

To meet the requirements of higher performance consumer electronics applications, Toshiba America Electronic Components (TAEC) announced that the company is expanding its offering of NAND Flash-based memory solutions with a family of High Speed SD Memory Cards capable of achieving a maximum write speed of 10 megabytes (MB)/second and a sustained write speed of 5 megabytes (MB)/second. Developed by Toshiba, the new memory cards feature a fivefold increase in data transfer rate over the company's standard SD Memory Cards and are targeted for demanding applications in digital video, digital audio, cellular phones, high resolution digital still cameras, PDAs, notebook computers, high-end digital still cameras, video cameras, mobile phones, USB Flash drives, car navigation systems, electronic books, MP3 players and other high-end portable electronics products.

The new High Speed SD Cards are initially available in densities of 128MB and 256MB, and are designated SD-F1284B1 and SD-F2564B1, respectively.

The industry-standard cards are packaged in the postage stamp sized SD card format, which measures 32mm x 24mm x 2.1mm. Toshiba's High Speed SD Memory cards are white to help users distinguish them from the company's standard SD Memory Cards, packaged in blue. A 512MB High Speed SD Memory Card is planned for Q1 2004.
