English: Secure Digital (SD) is a flash memory card format. It is based on the older Multi Media Card (MMC) format, but adds several features including write-protect switches. Standard SD cards measure 32 mm by 24 mm by 2.1 mm. There are several revisions of the original standard offering smaller sizes and/or improved performance.
