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.

Abstract: A flash memory controller includes a read/write unit, a state machine, a processing unit, and an auxiliary unit. The read/write unit is connected to a flash memory and performs a writing command or a reading command. The state machine is configured to determine a state of the flash memory controller. The processing unit is connected to the read/write unit and the state machine and configured to control the read/write unit. The auxiliary unit is connected to a first data line and a second data line and the processing unit and configured to receive and store a string output from the processing unit. The auxiliary unit outputs the string through the first and second data lines when the flash memory controller completes a writing data transmission.

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.

Abstract: A flash memory controller is provided. The flash memory controller includes a read/write unit, a state machine, a processing unit, and a reserve unit. The read/write unit is coupled to a flash memory. The read/write unit is configured to perform a write command or a read command. The state machine is configured to determine a state of the flash memory controller. The processing unit is coupled to the read/write unit and the state machine. The processing unit is configured to control the read/write unit. The reserve unit is coupled to a first data line, a second data line, and the read/write unit. When the flash memory controller is operating abnormally, the reserve unit receives an external signal via the first data line and the second data line and controls the read/write unit according to the external signal.
