SDRAM从发展到现在已经经历了五代,分别是:第一代SDR SDRAM,第二代DDR SDRAM,第三代DDR2 SDRAM,第四代DDR3 SDRAM,第五代,DDR4 SDRAM。第二,三,四代DDR(Double Data Rate)内存则采用数据读写速率作为命名标准,并且在前面加上表示其DDR代数的符号,PC-即DDR,PC2=DDR2,PC3=DDR3。如PC2700是DDR333,其工作频率是333/2=166MHz,2700表示带宽为2.7G。DDR的读写频率从DDR200到DDR400,DDR2从DDR2-400到DDR2-800,DDR3从DDR3-800到DDR3-1600。
