Design of High-speed and Mass Storage System Based on NAND Flash

In order to solve the problem of small-capacity and low-speed storage in the recording system,the solid NAND Flash with excellent performance is taken as a storage medium and large scale integrated circuit of FPGA as a control core.The application of parallel processing technology and pipeline technology makes the high-speed data storage achieved by several low-speed Flash,which improves the storage capacity and storage speed of the whole system.Aiming to the drawback of internal bad block in Flash,a set of processing mechanism for inquiring,updating and shielding bad block is established,thus the reliability of the data storage is improved.
