主存RAM是计算机系统中的重要部件之一,它品质的好坏直接影响到微机系统的整体性能。主存RAM在经历了SIP、DIP和SIMM几个阶段之后,现在正处于EDO DRAM与SD RAM(通常称为SDRAM)共存的时期。下面就分别谈谈这两种内存的简单知识。 EDO DRAM (Extended Data Out Dynamic RAM)意即扩展数据的动态随机存储器。它是在传统的DRAM的接口上增加了一些逻辑电路,以减少定位读取数据时的延时,从而提高了数据的存取速度。在 Main memory RAM is one of the important components in the computer system, its quality directly affects the overall performance of microcomputer system. After several stages of SIP, DIP and SIMM, the main memory RAM is in a period of coexistence of EDO DRAM and SDRAM (commonly referred to as SDRAM). The following talk about the two kinds of memory simple knowledge. EDO DRAM (Extended Data Out Dynamic RAM) Expansion of data that is, dynamic random access memory. It is in the traditional DRAM interface to increase the number of logic circuits to reduce the delay reading data positioning, thereby enhancing data access speed. in
