  半导体存储器芯片的译码驱动方式有几种？

  . 什么叫刷新？为什么要刷新？说明刷新有几种方法。

 说明存取周期和存取时间的区别

什么是存储器的带宽？若存储器的数据总线宽度为32位，存取周期为200ns，则存储器的带宽是多少？

 请画出以下概念之间的包含关系                                                                                                                                                                                                                                   

道密度=1/P     P为道距，即相邻两条磁道中心线之间的距离                                                                                                                                                                                                     位密度=f1/3.14*d（min） f1为每道总位数，d(min)为同心圆的最小直径                                                                                                                                                                                                                                                                                                 Dr=Db*V Db为记录密度，V是记录介质的运动速度
