Abstract: A method for accessing a flash memory device and a flash memory device. After receiving a write request for an address, a flash memory controller obtains an indicator of the address, where the indicator indicates a last access type of the address, which might be a write operation or a read operation. When determining the indicator indicates a write operation, which means the access type for the address is normally write operation, to save time, the flash memory controller perform a fast-write operation on the address, when the indicator indicates a read operation, which means there might be plenty of read operations on the address, to facilitate future read operation, the controller performs a slow-write operation on the address.
