Abstract: A Secure Digital (SD) card, and an system and an operating method for the SD card are disclosed. The disclosed SD card has a Flash memory and a controller. The Flash memory contains a data storage space and a Content Protection Recorded Media (CPRM) support space. The controller executes a firmware of the SD card, such that read/write commands provided from a host for the CPRM support space are regarded and executed as security commands and a CPRM mechanism is operated over the data storage space.
