SD Memory Cards
The SD memory card was jointly developed in 1999 by Toshiba Corporation, SanDisk Corporation and Matsushita Electric Industrial Co. Ltd. (best known for its Panasonic brand name products). SD memory cards have been widely adopted worldwide. Toshiba has shipped more than 300 million memory cards(8) and is currently the world's second largest supplier(9) of NAND Flash memory. The addition of the SDHC card to the Toshiba SD Card family addresses the growing demand for high capacity storage.
The Toshiba SD Memory Card family now includes standard SD memory cards, as well as miniSD, microSD and SDHC cards. The entire SD card line features cryptographic security, protection of copyrighted data, high-data transfer rate for fast copy/download and high storage capacity. TAEC currently offers SD Memory Cards with storage capacities of 1GB and 2GB in both its standard (blue) product family, and a higher performance (white) family of cards. The Toshiba SD Memory card line-up now includes miniSD in capacities ranging from 512MB to 2GB, microSDHC cards in capacities of 2GB and 4GB, and SDHC Cards in capacities of 4GB and 8GB.
