摘要
NAND Flash在现代数码产品中得到了广泛的应用,在片上系统芯片中集成NAND Flash控制器已成为一种趋势。分析SoC平台中高性能NAND Flash控制器的实现方案,提出两种改进NAND Flash控制器数据读写速度的技术,在面积增加很小的情况下,有效地改善了控制器的性能。该设计方法已通过了仿真测试和FGPA验证,在SMIC 0.18μm工艺库下的综合速度能够达到121MHz。
NAND Flash has been widely applied in modem digital products, it has become a trend to integrate an NAND Flash controller into SoC. In this paper, the implementation scheme of an NAND Flash controller with high performance on SoC platform is analysed, and two technologies for improving data access speed of NAND Flash controller are proposed. The performance of the controller is improved effectively at the cost of moderately higher area complexity. The design method has passed simulation test and FPGA verification, and in CMOS technology of SMIC 0.18 um standard, the operation frequency of controller achieves 121MHz.
