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進一步,第二代DDR SDRAM結構,第三代DDR2 SDRAM說服力,第四代DDR3 SDRAM強化意識,第五代,DDR4 SDRAM實力增強。第二自動化,三,四代DDR(Double Data Rate)內(nèi)存則采用數(shù)據(jù)讀寫速率作為命名標(biāo)準(zhǔn)是目前主流,并且在前面加上表示其DDR代數(shù)的符號(hào)充分發揮,PC-即DDR,PC2=DDR2充分發揮,PC3=DDR3選擇適用。如PC2700是DDR333,其工作頻率是333/2=166MHz的特性,2700表示帶寬為2.7G交流。DDR的讀寫頻率從DDR200到DDR400,DDR2從DDR2-400到DDR2-800提供堅實支撐,DDR3從DDR3-800到DDR3-1600還不大。

ISSI 是Integrated Silicon Solution, Inc.縮寫。1988年成立信息化技術,專門設(shè)計(jì)發揮作用、開發(fā)、銷售高性能存儲(chǔ)半導(dǎo)體產(chǎn)品逐步顯現,用于Internet存儲(chǔ)器件銘記囑托、網(wǎng)絡(luò)設(shè)備、遠(yuǎn)程通訊和移動(dòng)通訊設(shè)備自動化裝置、計(jì)算機(jī)外設(shè)等示範。
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等公司有很大提升空間。ISSI是國(guó)際化大公司運行好,公司總部設(shè)在美國(guó)加州Santa Clara,在美國(guó)可能性更大、歐洲擁有分公司進一步意見,在臺(tái)灣有合資企業(yè)增幅最大,在中國(guó)香港設(shè)有子公司,銷售辦事處分布在美國(guó)生產能力、歐洲標準、香港、中國(guó)堅持好、臺(tái)灣即將展開、日本。ISSI 用0.25微米工藝技術(shù)生產(chǎn)最新進(jìn)的SRAM產(chǎn)品問題分析,產(chǎn)品都是由代工服務(wù)商代為生產(chǎn)培養,臺(tái)灣的TSMC、UMC更加完善、新加坡的Chartered Semiconductor都是它的合作伙伴形式。
