摘　　要：介绍了一种可应用于固态硬盘(Solid State Disk)主控芯片中的闪存控制器的设计实现方法。该闪存控制器最大支持4路闪存通路,4路闪存通路共用一个ECC纠错模块,提出一种新型可编程控制方法,CPU可实现4路闪存数据的并发读写,并兼容多种品牌的闪存颗粒。主要介绍了该闪存控制器的硬件架构及关键模块的设计实现思路,并最终给出了闪存控制器的验证结果及综合结果,在多种纠错格式及4路通路的配置下,闪存控制器的性能及成本均能满足一般SSD主控芯片的使用需求。An effective design and implementation method of NAND flash memory host controller that implemented in Solid State Disk controller was analyzed in this paper. The NAND flash memory host controller supports up to 4 channels NAND flash ports,with 4 channels NAND flash port sharing one ECC error correction module. By using a new type of programmable control method,the CPU can realize 4 channels read and write flash memory data concurrent, and is compatible with a variety of brands of NAND flash. The design philosophy of hardware architecture and critical modules was introduced. The verification and synthesis results were demonstrated finally. Considering of performance and cost evaluation, general SSD controllers could be satisfied by this controller which configured with 4 flash channels and multiple ECC coding formats.
