【产品】工作电压1.8V的DDR2，数据传输速度高达800mt/s

时间： 2019-12-10 来源：ATP

技术问答

ATP DDR2以高达800mt/s的数据传输速度取代了原来的DDR规格。与第一代DDR相比，工业DDR2 SDRAM的内存时钟速度降低了一半，使DDR2能够有效地运行到DDR总线速度的2倍。

除了运行速度快之外，DDR2比它的前辈消耗更少的电能。DDR2的工作电压从2.5V降低到1.8V，降低了总功耗。

ATP DDR2模块有多种形式，适合不同的应用，包括240 Pin全尺寸DIMM、200 Pin SODIMM、244 Pin miniDIMM和240 pin FB-DIMM。窄板型(VLP DIMM和 mini-UDIMM 适用于紧凑型的系统。DDR2内存模块不能与DDR、DDR3或DDR4互换使用。
