DDR SDRAM 是Double Data Rate Synchronous Dynamic Random Access Memory(双数据率同步动态随机存储器)的简称,是由VIA等公司为了与RDRAM相抗衡而提出的内存标准。DDR SDRAM是SDRAM的更新换代产品,采用2.5v工作电压,它允许在时钟脉冲的上升沿和下降沿传输数据,这样不需要提高时钟的频率就能加倍提高SDRAM的速度,并具有比SDRAM多一倍的传输速率和内存带宽,例如DDR 266与PC 133 SDRAM相比,工作频率同样是133MHz,但内存带宽达到了2.12 GB/s,比PC 133 SDRAM高一倍。目前主流的芯片组都支持DDR SDRAM,是目前常用的内存类型。 DESCRIPTION描述The Hynix HY5DU561622ETP is a 268,435,456-bit CMOS Double Data Rate(DDR) Synchronous DRAM, ideally suitedfor the point-to-point applications which requires high bandwidth.The Hynix 16Mx16 DDR SDRAMs offer fully synchronous operations referenced to both rising and falling edges of theclock. While all addresses and control inputs are latched on the rising edges of the CK (falling edges of the /CK), Data,Data strobes and Write data masks inputs are sampled on both rising and falling edg
