摘要
A data accessing method, and a storage system and a controller using the same are provided. The data accessing method is suitable for a flash memory storage system having a data perturbation module. The data accessing method includes receiving a read command from a host and obtaining a logical block to be read and a page to be read from the read command. The data accessing method also includes determining whether a physical block in a data area corresponding to the logical block to be read is a new block and transmitting a predetermined data to the host when the physical block corresponding to the logical block to be read is a new block. Thereby, the host is prevented from reading garbled code from the flash memory storage system having the data perturbation module.
