Abstract
A data read method for reading data to be accessed by a host system from a plurality of flash memory modules is provided. The data read method includes receiving command queuing information related to a plurality of host read commands from the host system, each of the host read commands is corresponding to one of a plurality of data input/output buses coupled to the flash memory modules. The data read method also includes re-arranging the host read commands and generating a command giving sequence according to the data input/output buses corresponding to the host read commands. The data read method further includes sequentially receiving and processing the host read commands from the host system according to the command giving sequence and pre-reading data corresponding to a second host read command. Thereby, the time for executing the host read commands can be effectively shortened.
