SDRAM從發(fā)展到現在已經經歷了五代,分別是: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)內存則采用數據讀寫速率作為命名標準,并且在前面加上表示其DDR代數的符號,PC-即DDR,PC2=DDR2,PC3=DDR3。如PC2700是DDR333,其工作頻率是333/2=166MHz,2700表示帶寬為2.7G。DDR的讀寫頻率從DDR200到DDR400,DDR2從DDR2-400到DDR2-800,DDR3從DDR3-800到DDR3-1600。
ISSI 是Integrated Silicon Solution, Inc.縮寫。1988年成立,專門設計、開發(fā)、銷售高性能存儲半導體產品,用于Internet存儲器件、網絡設備、遠程通訊和移動通訊設備、計算機外設等。
