A method of controlling an access time for accessing a flash memory comprises comparing a target address of the flash memory with an address of the flash memory that was previously accessed; setting the access time for the flash memory to be a first access time if the target address does not correspond to the same page of the flash memory as the previous address; and setting the access time for the flash memory to be a second access time if the target address corresponds to the same page of the flash memory as the previous address, the first access time being greater than the second access time.
