Summary:A method for improving the read efficiency of a flash memory under RAID protection includes a memory control chip. A memory control chip is provided with a plurality of protective data buffers, a plurality of data buffers and a flash memory instruction control means. The flash memory instruction control device is connected with the plurality of data protection buffers and the plurality of data buffers, and the memory control chip is connected with a plurality of flash memories. In the present invention, the read flash memory is not affected by the protection data in any channel when the continuous data in the flash memory is read, and the efficiency of reading the flash memory is improved. Compared with the traditional method of writing protected data in the same channel, this method can make full use of the advantages and efficiency of the channel, and improve the efficiency of reading flash memory by 12.5%. 本发明公开了种RAID保护下提升闪存读取效能方法，包括存储器控制芯片，存储器控制芯片内设有多个保护数据缓冲区、多个数据缓冲区和闪存指令控制装置，闪存指令控制装置分别连接多个数据保护缓冲区和多个数据缓冲区
