RAM:由字面意思就可以理解,SDRAM SRAM DRAM(下面蓝色字体的这几种)都可以统称RAM,random access memory(随机存取存储器)的缩写,下面是51hei.com为大家整理的目前所有的存储器的区别.SRAM:静态随机存储器,就是它不需要刷新电路,不像动态随机存储器那样,每隔一段时间就要刷新一次数据.但是他集成度比较低,不适合做容量大的内存,一般是用在处理器的缓存里面.像S3C2440的ARM9处理器里面就有4K的SRAM用来做CPU启动时用的.DRAM,动态随机存取

                      SRAM/DRAM,PROM/EPROM/EEPROM,NOR/NAND FLASH区别 RAM / ROM 存储器 ROM和RAM指的都是半导体存储器,ROM是Read Only Memory的缩写,RAM是Random Access Memory的缩写.ROM在系统停止供电的时候仍然可以保持数据,而RAM通常都是在掉电之后就丢失数据,典型的RAM就是计算机的内存. RAM 有两大类: 1) 静态RAM(Static RAM / SRAM),SRAM

ROM指的是"只读存储器",即Read-Only Memory.这是一种线路最简单半导体电路,通过掩模工艺, 一次性制造,其中的代码与数据将永久保存(除非坏掉),不能进行修改.这玩意一般在大批量生产时才会被用的,优点是成本低.非常低,但是其风险比较大,在产品设计时,如果调试不彻底,很容易造成几千片的费片,行内话叫"掩砸了"! PROM指的是"可编程只读存储器"既Programmable Red-Only Memory.这样的产品只允许写入一次,所

ROM(Read Only Memory,只读存储器)芯片:在微机的发展初期,BIOS都存放在ROM芯片中.ROM内部的资料是在ROM的制造工序中,在工厂里用特殊的方法被烧录进去的,其中的内容只能读不能改,一旦烧录进去,用户只能验证写入的资料是否正确,不能再作任何修改.如果发现资料有任何错误,则只有舍弃不用,重新订做一份.ROM是在生产线上生产的,由于成本高,一般只用在大批量应用的场合. PROM(Programmable ROM,可编程ROM)芯片:由于ROM制造和升级的不便,后来人们发明了P
