Abstract: An intelligent detection device of solid state hard disks combining a plurality of NAND flash memory card, and detecting method for the same. Wherein, a central processing unit (CPU) controls a control unit, and is connected electrically to a plurality of flash card insertion slots, for a plurality of NAND flash memory card to be inserted in. Said control unit reads parameters of said flashcards, and transmits said parameters back to said CPU, for it to determine status of each said NAND flash memory card, and display status of each said NAND flash memory card on at least a status display unit. Said intelligent detection device is capable of integrating storage space of a plurality of NAND flash memory card into a larger storage space, and detecting status of each said NAND flash memory card, to inform users to backup data in time.

Abstract: A composite solid state drive control system, composed of a redundant array of independent disks (RAID) formed by SD Cards, and multi-channel Flash Memory. Wherein, at least a RAID control unit combines a plurality of relatively inexpensive SD Cards into a set of redundant arrays of independent disks (RAIDs), so that its storage capacity can reach or even surpass a costly and huge capacity SD Card. Through controlling data transmission and accessing between at least a flash memory control unit and at least a SD Card control unit, data read and write speeds can be increased, and back-up redundant data can be made, hereby achieving stable operations of an electronic computing device by means of highly stable Flash Memory.

Abstract: The present invention relates to a detection method used in a memory card adaptor and, more particularly, to a detection method used in an adaptor capable of inserting various kinds of memory cards. 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: A memory array apparatus with shorter data accessing time is proposed. The memory array apparatus comprises a register administrator and a plurality of data registers between a micro controller and at least one memory array. The data to be accessed are divided into a plurality of data blocks according to a predetermined data unit. The data block is firstly stored in corresponding data register and then read by the main frame or stored into the corresponding memory array. At the same time, the next data block is stored in the corresponding data register through circuit switched by the micro controller. The pending time of the main frame and the data accessing time can be advantageously reduced.

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.

Abstract: The present invention proposes a control device compatible to Smart Media cards, Memory Stick cards, and NAND-gate type flash memories and applicable to various kinds of capacities and a method for fabricating same. After the control device is turned on and scans physical block addresses of each data block of a memory card one by one, it will partition the memory card into a plurality of segments according to the capacity of a segment lookup table therein. A FAT accessory lookup table in the control device is matched and used for lookup of logical addresses of the FAT. When a host computer is to access a file, the segment lookup table can be used for lookup of data in the segment, and the FAT accessory lookup table will match the operation system to quick find the physical block address when the FAT is accessed. The control device can be compatible to flash memory cards of various kinds of capacities, and the required size of the size of total lookup tables built in RAM can be effectively controlled.

Abstract: A RAID device has command processing and data transmission adapting ability. The RAID device comprises a RAID controller connected to a host computer through a bus, and a plurality of hard disks. The RAID controller comprises a controller, a selection switch, a command register, a data hub. The controller is connected to all other components of the RAID controller. The controller processes command and regulates channel for data transmission such that the data is directly accessed between CPU and storage disk. The buffer memory is saved and the data can be rebuilt to reduce the risk of computer failure.
