摘要： A data protection method for a flash memory device. In one embodiment, the flash memory device comprises a flash memory for storing protected data. After the flash memory device is coupled to a host, a plurality of current read addresses of a plurality of read commands sent from the host to the flash memory device are recorded. The current read addresses are then compared with a plurality of predetermined read addresses. When the current read addresses are not identical to the predetermined read addresses, the flash memory device is made to enter a data protection mode. When the flash memory device is in the data protection mode, if the flash memory device receives a plurality of data access commands, the data access commands are processed according to a protection mode setting parameter to prevent the protected data from being accessed by the host.

摘要： A data processing method for a non-volatile memory device is provided. The non-volatile memory device includes a controller and a NAND flash memory. First, a target command and a corresponding target address are serially transmitted from the controller to the NAND flash memory. Then, the NAND flash memory calculates a first value according to the target address. Moreover, a cyclic redundancy check code corresponding to the target address is transmitted from the controller transmits to the NAND flash memory. Next, the NAND flash memory determines whether a transmission error has occurred by performing a cyclic redundancy check according to the first value and the cyclic redundancy check code. When the transmission error has occurred, a status register is set to inform the controller to re-transmit the target command and the corresponding target address.
