从1970年Intel发布第一片IKB的DRAM芯片至今已经过去了近30年。DRAM的结构历经了普通页方式(Page mode)、静态列方式(Static column mode)、快速页方式(Fast Page mode)、EDO、SDRAM等多种方式。虽然DRAM的容量和速度在不断地提高,但是从体系结构上看,并没有发生根本的变化,它们可以被视为传统的DRAM存储器。由于受到种种限制,传统DRAM的结构 It has been nearly 30 years since Intel released the first IKB DRAM chip in 1970. The structure of DRAM has gone through many modes such as Page mode, Static column mode, Fast Page mode, EDO, SDRAM and so on. Although DRAM capacity and speed continue to improve, but from the architectural point of view, there is no fundamental change, they can be regarded as the traditional DRAM memory. Due to a variety of restrictions, the structure of traditional DRAM
