A data protecting method for a portable memory storage apparatus is provided. The method includes determining whether a mode signal is at a data protecting mode, and performing a file hiding procedure to change a file allocation table if the mode signal is at the data protecting mode, wherein a host system coupled to the portable memory storage device is allowed to only access a portion of logical addresses of the portable memory storage apparatus according to the changed file allocation table and files stored in the portable memory storage apparatus before the file hiding procedure are written into another portion of the logical addresses. Additionally, the method still includes performing a file showing procedure to change the file allocation table if the mode signal is not at the data protecting mode, wherein the host system may access all the logical addresses according to the changed file allocation table.

Method of hiding file at data protecting mode for non-volatile memory module, memory controller and portable memory storage apparatus

A system, a controller, and a method for data storage are provided. The system includes a first storage unit, a second storage unit, and a controller. The first storage unit comprises a single-layer structure for storing data, and the second storage unit comprises a multi-layer structure for storing data. The controller is coupled to the first storage unit, the second storage unit, and a host and controls the host to set the first storage unit as a master storage device and set the second storage unit as a slave storage device. As a result, the host can recognize the first storage unit and the second storage unit as two independent storage devices for storing data. Thereby, the data storage process can be simplified.

System, controller, and method for data storage

A flash storage chip including a single circuit board, a microcontroller, a flash memory, and a peripheral component interconnect express (PCI Express) connecting interface is provided. The microcontroller, the flash memory, and the PCI Express connecting interface are embedded on the single circuit board, and the microcontroller has a flash memory interface and a PCI Express interface. When a host writes a data into the flash storage chip, the microcontroller receives the data though the PCI Express interface and stores the data into the flash memory though the flash memory interface. When the host reads a data form the flash storage chip, the microcontroller reads the data from the flash memory though the flash memory interface and transmits the data to the host though the PCI Express interface and the PCI Express connecting interface.
