自从有了电脑,就有了内存。存储器的发展也经历了很多技术上的改进,从早期的DRAM到FPMDRAM、EDODRAM、SDRAM等。,内存的速度一直在提高,容量一直在增加。现在的服务器主要用什么内存?注册ECC SDRAM广泛应用于IA架构服务器。
存储器是数字系统中用来存储大量信息的器件或元件,是计算机和数字设备的重要组成部分。存储器可分为随机存取存储器(RAM)和只读存储器(ROM)。
随机存取存储器(RAM)不仅可以在单元中存储信息,还可以从单元中读取信息。任何存储在RAM中的信息在断电后都会丢失,所以RAM是易失性存储器。
ROM是只读存储器。除了存储数据、表格和固化程序外,它还广泛应用于组合逻辑电路中。
波动性
当电源关闭时,RAM无法保存数据。如果需要保存数据,必须将数据写入长期存储设备(如硬盘)。
RAM的工作特点是上电后可以随时访问任意位置单元的数据和信息,断电后内部信息消失。
random access
The so-called "random access" means that when the data in the memory is read or written, the time required has nothing to do with the location where the information is located or the location where it is written. On the contrary, when reading or writing information in a Sequential Access storage device, the time required is related to the location. It is mainly used to store the operating system, various applications, data and so on.
When the RAM is in normal operation, data can be read from or written into the RAM. Compared with ROM, RAM has the advantages of convenient reading/writing and flexible use, which is especially suitable for frequent and rapid data replacement.
