The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. January 2000 to promote and create SD Card standards.

SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. Secure Digital includes four card families available in three different sizes. The three form factors are the original size, the mini size, and the micro size.

Memory passive windows allow a smaller card to fit and function controller a device built host a larger 7. The SD card’s ricoh footprint is an ideal storage stick for smaller, thinner and more portable electronic devices. This section does not cite any 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 card’s electrical contacts are recessed beneath the surface of the card, protecting them from contact with a user’s fingers.

The SD specification envisioned capacities and transfer rates exceeding those of MMC, and both of these functionalities have grown over time. For a comparison table, see below. While MMC uses a single pin for data transfers, the SD card added a four-wire bus mode for higher data rates. Full-size SD cards do not fit into the slimmer MMC slots, and other issues also affect the ability to use one format in a host device designed for the other.

January 2006 and defined in version 2. 0 of the SD specification, supports cards with capacities up to 32 GB.

The SDHC trademark is licensed to ensure compatibility. SDHC cards are shipped preformatted with the FAT32 file system.

SDHC host devices are required to accept older SD cards. However, older host devices do not recognize SDHC or SDXC memory cards, although some devices can do so through a firmware upgrade. Older Windows operating systems released before Windows 7 require patches or service packs to support access to SDHC cards. January 2009 and defined in version 3. 32 GB for SDHC cards in the SD 2.

SDXC adopts Microsoft’s exFAT file system as a mandatory feature. UHS-II bus, which requires an additional row of physical pins.

2016, and added «Video Speed Class» ratings for UHS cards to handle higher resolution video formats like 8K. This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources.

Unsourced material may be challenged and removed. SDXC cards utilize the exFAT file system, the use of which is governed by a proprietary license, thereby limiting its legal availability to a small set of operating systems. Therefore, exFAT-formatted SDXC cards are not a universally readable exchange medium.

FAT out of the box. Nevertheless, in order to be fully compliant with the SDXC card specification, many SDXC-capable host devices are firmware-programmed to expect exFAT on cards larger than 32 GB. Therefore, even if a file system is supported in general, it is not always possible to use alternative file systems on SDXC cards at all depending on how strictly the SDXC card specification has been implemented in the host device.

This bears a risk of accidental loss of data, as a host device may treat a card with an unrecognized file system as blank or damaged and reformat the card. The SD Association provides a formatting utility for Windows and Mac OS X that checks and formats SD, SDHC, and SDXC cards.

Specified in SD version 3. 01, and is mandatory for microSDHC and microSDXC cards labeled as UHS-I.
