Abstract: A data storage device having multiple buffers is proposed. When storing data, a controller makes use of a host's bus to select and transmit multiple block data to multiple buffers for temporary storage and then records relevant details. Next, the controller transmits the data from the buffers to a storage connected with the controller. When retrieving data, the controller selects the data from the storage and temporarily stores the data in the buffers and then records relevant details. Subsequently, the controller transmits the data to the host. The controller is used to control the operations of the host, the buffers, and the storage. Multiple buffers are exploited to achieve the maximum bandwidth of the transmission interface of the host to increase the transmission speed.

The present invention comprises mainly the steps of: a control device on an adaptor issuing an identification command to detect a memory card responsive to the identification command, and the control device issuing again a reset command to detect a reset-type memory card if there is no corresponding response; the control device continually awaiting a response signal if there is still no corresponding response; the control device entering a read/write mode corresponding to the memory card if a corresponding response is obtained after issuing the command; and the control device awaiting a read/write command of said master device. The present invention can effectively enhance detection and identification efficiency without the need of adding a hardware switching device.

Abstract: The present invention relates to an algorithm of flash memory capable of quickly building a mapping table and preventing disorder of data due to abnormal disconnection and a control system thereof, wherein pages of a physical block store data of the mapping table of logical block addresses and corresponding physical block addresses. A set of ECC data are used for protection. When the host computer is normally turned on, data of the mapping table are directly stored into a buffer so that the control device can read. The system can quickly build the mapping table to save the time and operation of turning on without the need of a scanning procedure. If an error of the mapping table due to improper operation occurs, the previous mapping table can be retraced to restore the system to the normal state.
