     SDRAM從發(fā)展到現(xiàn)在已經(jīng)經(jīng)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。第一代SDRAM采用單端（Single-Ended）時鐘信號,第二代、第三代與第四代由于工作頻率比較快，所以采用可降低干擾的差分時鐘信號作為同步時鐘。SDR SDRAM的時鐘頻率就是數(shù)據(jù)存儲的頻率，數(shù)據(jù)讀寫速率也為100或133MHz。

 
ISSIISSI 是Integrated Silicon Solution, Inc.縮寫。1988年成立，專門設(shè)計、開發(fā)、銷售高性能存儲SRAM半導(dǎo)體產(chǎn)品，用于Internet存儲器件、網(wǎng)絡(luò)設(shè)備、遠(yuǎn)程通訊和移動通訊設(shè)備、計算機外設(shè)等。
       公司的客戶都是一些電子工業(yè)巨頭，如3Com, Alcatel, Cisco, Ericsson, Hewlett Packard, IBM, Lexmark, Motorola, Nokia, Seagate等公司。ISSI是國際化大公司，公司總部設(shè)在美國加州Santa Clara，在美國、歐洲擁有分公司，在臺灣有合資企業(yè)，在中國香港設(shè)有子公司，銷售辦事處分布在美國、歐洲、香港、中國、臺灣、日本。ISSI 用0.25微米工藝技術(shù)生產(chǎn)最新進的SRAM產(chǎn)品，產(chǎn)品都是由代工服務(wù)商代為生產(chǎn)，臺灣的TSMC、UMC、新加坡的Chartered Semiconductor都是它的合作伙伴。
