Abstract: The present invention provides a method for controlling a data storage device. The data storage device includes a flash memory controller and a flash memory module. The flash memory controller has a first buffer memory and a second buffer memory. The memory module has at least a first memory portion and a second memory portion. The method includes: receiving a first data from a host device; storing the first data in the first buffer memory; transmitting the first data to the first memory portion of the flash memory module from the first buffer memory; and transmitting the first data to a host memory buffer in the host device from the first buffer memory. The first data corresponds to at least a portion of a second data to be written to the second memory portion.
