Abstract
A method for reading data from a flash memory is provided. The method comprises: determining whether a host device is requesting a sequential read access to the flash memory; prior to receiving a first host read command issued by the host device, performing a read-ahead operation to read data from the flash memory according to a read-ahead start logical block address (LBA) if the host device is requesting the sequential read access to the flash memory; and storing the data that is read through the read-ahead operation in a read-ahead buffer; and in response to receiving a first host read command issued by the host device, sending a portion or all of data that is read through the read-ahead operation to the host device if a start LBA of the first host read command corresponds to one of start LBAs of data that is stored in the read-ahead buffer.
