随着电子技术的发展，我们会经常听到ROM、RAM这种词汇。RAM指的是随机存取存储器，是Random Access Memory首字母缩写。特点是能够与CPU直接进行数据交互，存储着局部变量数据。ROM指的是只读存储器，是Read-Only Memory的首字母缩写。数据写入后只能读取，掉电不丢失。

这些都是比较抽象的专业名词了，特别是寄存器，很多人在学单片机的时候对这个一脸懵逼，寄存器到底是个啥玩意？ 其实不用很深刻的理解它到底是什么，你只需要知道通过配置寄存器的值，就可以把外设用起来。 我做单片机开发的这10几年，接触寄存器非常 ...

前几天偶然之间与同事谈论到ROM，RAM,FLASH一些知识，而突然之间当我们去说这些英文单词的话还真是粗浅的知道，而在我们当中的MCU一些含义也不甚清楚，索性今天晚上就来汇总这方面的知识。 ROM和RAM指的都是半导体存储器，ROM是Read Only Memory的缩写，RAM是Random ...

一、ROM：只读存储器，内容写入后就不能更改了，制造成本比较低，常用于电脑中的开机启动如启动光盘bios，在系统装好的电脑上时，计算机将C盘目录下的操作系统文件读取至内存，然后通过cpu调用各种配件进行工作这时系统存放存储器为RAM。 PROM：可编程程序 ...

What Are The Difference Between Ram And Rom? RAM (Random Access Memory) is a type of memory that temporarily stores the data you're currently using, but it's volatile, meaning its contents are erased ...

Like peanut butter and jelly, like salt and pepper, like that seemingly perfect couple you love (to hate), the two dominant types of computer memory truly complete one another. Read-only memory (ROM) ...

When we learn about the internals of a microprocessor, we are shown a diagram that resembles the 8-bit devices of the 1970s. There will be an ALU, a program counter, a set of registers, and address ...

Let us discuss this topic in more detail. 1] Hard Disk Drive (HDD) or Solid-State Drive (SSD) When it comes down to common computer memory, the hard disk drive is likely at the top of the list. If you ...
