Abstract: A Secure Digital (SD) card, and an operating 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.

Abstract: A storage medium receiving write data provided by a host device, providing read data to the host and including a first module and a second module is disclosed. The first module includes a first memory cell and a first controller. The first memory cell stores the write data. The first controller reads the first memory cell to generate a first accessing result. The second module includes a second memory cell and a second controller. The second memory cell stores the write data. The second controller reads the second memory cell. When the first accessing result has an error and the error cannot be corrected by the first controller, the first controller requests the second controller to read the second memory cell to generate a second accessing result, and the second controller serves the second accessing result as the read data and provides the read data to the host.
