SD Association

The SD Association (SDA) is an American nonprofit organization that sets standards for the SD memory card format. SanDisk, Panasonic (Matsushita), and Toshiba formed the SD Association in January 2000. In 2010, the SDA had approximately 1,000 member companies involved in the design and development of SD standards. Thousands of device models and hundreds of products across dozens of product categories integrate the small, removable memory cards.

The SD Association develops industry standards that define the next generation of SD cards and guide manufacturers in developing new products. This strategy has made the SD memory card the most widely used removable memory card form factor in the industry.
