At present, the DDR2 with its and high data transfer rate and low cost are more and more used in some high-end consumer electronics and portable products. Processing of DDR2 SDRAM controller design becomes and is very necessary. Digital circuit design using FPGA technology, not only can simplify the design process, but also can reduce the size and cost of the whole system, increase the reliability of the system. This design USES Altear company Cyclone V generation device, the smallest system development. This design USES the Mircon MT47 series chips, and IP core provided by Altera corporation how can automatically generate the PHY interface. Driven requirements due to DDR2, speaking, reading and writing, and design the voltage requirements for many times. in this paper, the basic structure and principle of DDR2 SDRAM has carried on the simple introduction. And in this paper, the DDR2 design method based on FIFO and PHY interface Key Words DDR2 FPGA memory controlle FIFO 第 I 页 共 I 页 本 科 毕 业 设 计 第 I 页 共 I 页 TOC \o 1-3 \h \u 动态随机存储器原理与结构 3 动态
