Abstract: A method for accessing data is provide, the method includes: receiving a first address and identification information used to identify an address type; and when the identification information indicates a logical address type, converting the first address into a first physical address, and accessing at least one corresponding flash memory chip in the storage device; or when the identification information indicates a physical address type, directly accessing at least one corresponding flash memory chip in the storage device. When the storage device is accessed, a type of an accessed address is determined according to the identification information. If the address is a logical address, the storage controller maps the logical address to a physical address and accesses the physical address; or if the address is a physical address, the storage controller directly accesses the physical address sent by the host.
