     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。第一代SDRAM采用单端(Single-Ended)时钟信号,第二代、第三代与第四代由于工作频率比较快,所以采用可降低干扰的差分时钟信号作为同步时钟。SDR SDRAM的时钟频率就是数据存储的频率,数据读写速率也为100或133MHz。

 
ISSIISSI 是Integrated Silicon Solution, Inc.缩写。1988年成立,专门设计、开发、销售高性能存储SRAM半导体产品,用于Internet存储器件、网络设备、远程通讯和移动通讯设备、计算机外设等。
       公司的客户都是一些电子工业巨头,如3Com, Alcatel, Cisco, Ericsson, Hewlett Packard, IBM, Lexmark, Motorola, Nokia, Seagate等公司。ISSI是国际化大公司,公司总部设在美国加州Santa Clara,在美国、欧洲拥有分公司,在台湾有合资企业,在中国香港设有子公司,销售办事处分布在美国、欧洲、香港、中国、台湾、日本。ISSI 用0.25微米工艺技术生产最新进的SRAM产品,产品都是由代工服务商代为生产,台湾的TSMC、UMC、新加坡的Chartered Semiconductor都是它的合作伙伴。
