在計(jì)算機(jī)的結(jié)構(gòu)中,有一個(gè)非常重要的部分,那就是內(nèi)存。內(nèi)存是用來(lái)存儲(chǔ)程序和數(shù)據(jù)的部件。
就電腦而言,有了內(nèi)存,就有了保證正常工作的記憶功能。
在計(jì)算機(jī)中,RAM和ROM都是數(shù)據(jù)存儲(chǔ)器。RAM是一種隨機(jī)存取存儲(chǔ)器,它的特點(diǎn)是易失性,即掉電和失憶。
ROM usually refers to solidified memory (write once, read repeatedly), and its characteristics are opposite to RAM. For example, if a file is closed due to sudden power failure or unsaved, ROM can randomly save the previously unsaved file, but RAM will make the previously unsaved file disappear.
Random Access Memory (RAM), also called main memory, is an internal memory that directly exchanges data with CPU. It can be read and written at any time (except when it is refreshed), and it is very fast. It is usually used as a temporary data storage medium for the operating system or other running programs. RAM can write (store) or read (take out) information from any address at any time when it is working. The difference between it and ROM is the volatility of data, that is, once the power is cut off, the stored data will be lost. RAM is used in computers and digital systems to temporarily store programs, data and intermediate results.
靜態(tài)存儲(chǔ)單元是在靜態(tài)觸發(fā)器的基礎(chǔ)上增加門(mén)控制而形成的。因此,它通過(guò)觸發(fā)器的自我保護(hù)功能來(lái)存儲(chǔ)數(shù)據(jù)。SRAM中存儲(chǔ)的信息可以長(zhǎng)時(shí)間保存而不會(huì)斷電,狀態(tài)穩(wěn)定,因此簡(jiǎn)化了外部電路設(shè)計(jì)。但是由于SRAM的基本存儲(chǔ)電路包含很多晶體管,集成度低,功耗高。
我們承諾:將回收的服務(wù)器和電腦硬盤(pán)全部格式化,讓您的數(shù)據(jù)更放心,不泄露。
