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.

Abstract: A method of a flash controller to be coupled between a flash memory device and a host device is provided. The flash memory device has a plurality of blocks each having a plurality of pages, and the method comprises: receiving a trim/erase/unmap command from the host device; obtaining a storage space, which is to be erased, from the trim/erase/unmap command; comparing a space size of the storage space with a threshold to determine whether the space size is larger than the threshold; and resetting valid page counts of the plurality of blocks of the flash memory device when the space size is larger than the threshold.

Abstract: A method and apparatus for performing data storage management to enhance data reliability are provided. The method includes: receiving a write command from a host system, wherein the write command indicates that writing a set of data into a non-volatile (NV) memory is required; determining whether a repeated writing condition is satisfied, wherein the repeated writing condition includes the write command being a repeated write command of a previous write command and corresponding to a same address and a same length as that of the previous write command; and in response to the repeated writing condition being satisfied, storing the set of data into at least one of a first type of blocks within the NV memory, for performing data storage enhancement processing, wherein bit count per memory cell of the first type of blocks is less than bit count per memory cell of a second type of blocks.

Abstract: A storage medium including a first transmittal module and a control module. The first transmittal module includes a plurality of first transmittal pads. The control module determines whether a level state of the first transmittal module is equal to a pre-determined state. When the level state is equal to the pre-determined state, the control module operates in a secure digital (SD) mode. When the level state is not equal to the pre-determined state, the control module operates in an embedded multimedia card (eMMC) mode.

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.
