The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. Developers predicted that DRM would induce wide use by music suppliers concerned about piracy. For this reason the D within the logo resembles an optical disc. The SD Association, headquartered in San Ramon, California, United States, started with about 30 companies and today consists of about 1,000 product manufacturers that make interoperable memory cards and devices. Early samples of the SD Card became available in the first quarter of 2000, with production quantities of 32 and 64 MB 7 cards available three months later. While the new cards were designed especially for mobile phones, they are usually packaged with a miniSD adapter that provides compatibility with a standard SD memory card slot. TransFlash and microSD cards are functionally identical allowing either to operate in devices made for the other. SanDisk had conceived microSD when its chief technology officer and the chief technology officer of Motorola concluded that current memory cards were too large for mobile phones. At CTIA Wireless 2005, the SDA announced the small microSD form factor along with SDHC secure digital high capacity formatting in excess of 2 GB 11 (2000 MB) with a minimum sustained read and write speed of 17.6 Mbits. SanDisk induced the SDA to administer the microSD standard. The SDA approved the final microSD specification on July 13, 2005. Initially, microSD cards were available in capacities of 32, 64, and 128 MB. Beneath it is a section of a magnetic-core memory (used until the 1970s) that holds eight bytes using 64 cores. Devices that support miniSDHC work with miniSD and miniSDHC, but devices without specific support for miniSDHC work only with the older miniSD card. At the same show, SanDisk and Sony also announced a comparable Memory Stick XC variant with the same 2 TB maximum as SDXC, 14 and Panasonic announced plans to produce 64 GB SDXC cards. On March 6, Pretec introduced the first SDXC card, 16 a 32 GB card with a readwrite speed of 400 Mbits. But only early in 2010 did compatible host devices come onto the market, including Sony s Handycam HDR-CX55V camcorder, Canon s EOS 550D (also known as Rebel T2i) Digital SLR camera, 17 a USB card reader from Panasonic, and an integrated SDXC card reader from JMicron. The earliest laptops to integrate SDXC card readers relied on a USB 2.0 bus, which does not have the bandwidth to support SDXC at full speed. The cards are essentially full-size SDHC or SDXC UHS-II cards, rated at UHS Speed Class U1. An adapter allows MicroP2 cards to work in current P2 card equipment. Panasonic MicroP2 cards shipped in March 2013 and were the first UHS-II compliant products on market; initial offer includes a 32GB SDHC card and a 64GB SDXC card. Later that year, Lexar released the first 256 GB SDXC card, based on 20 nm NAND flash technology. Micro Sd Card Series For MicroSDIn June 2018 Kingston announced the Canvas series for MicroSD cards which both are capable of capacities up to 512 GB, in three variations, Select, Go, and React. In February 2019, Micron and SanDisk unveiled their microSDXC cards of 1 TB capacity. The five families are the original Standard-Capacity (SDSC), the High-Capacity (SDHC), the eXtended-Capacity ( SDXC ), the Ultra-Capacity ( SDUC ) and the SDIO, which combines inputoutput functions with data storage. The three form factors are the original size, the mini size, and the micro size. Electrically passive adapters allow a smaller card to fit and function in a device built for a larger card. ![]() Please help improve this section by adding citations to reliable sources.

The SD specification defines a card called Thin SD with a thickness of 1.4 mm, but they occur only rarely, as the SDA went on to define even smaller form factors. The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in version 2.0 (see below ), and the fact that SDHC cards are shipped preformatted with the FAT32 file system.
