What are the characteristics of ram?

Characteristics of ram: 1. Access speed. Among all current access devices, random access memory is almost the fastest; 2. Random access, the time or location of data being read, written or written. They are all random and not fixed; 3. It is easy to lose. When the power of the computer is turned off, the random access memory cannot retain the data.

Characteristics of ram:

ram is an internal memory that directly exchanges data with the CPU. RAM memory can write or read information from any specified address at any time. It can be read and written at any time (except when refreshing), and it is fast and is often used as a temporary data storage medium for operating systems or other running programs. Whether it is a mobile phone or a computer, the running speed often depends on the size of RAM, that is, running memory.

Friends who often come into contact with computers should know that the inside of a computer is divided into memory and external memory. The so-called memory is actually also called main memory, which is what we often call the internal hard drive. The RAM we are going to introduce today, the random access memory, is directly connected to the core central processing unit (CPU) of the computer. During the operation of the computer, random access memory is used to store, read and write information and data. It can satisfy the memory storage generated by the running of applications when people surf the Internet. Yingshang Micro is an agent of major brands of memory (SRAM, MRAM, psram, SDRAM, etc.).

ram features are as follows:

#1. Access speed: The biggest advantage is the user’s speed when reading or writing data. The speed is the fastest. Among all current access devices, random access memory is almost the fastest. The access delay and access delay caused by some access devices during operation are almost negligible. This feature It also greatly improves the working efficiency of ram;

2. Random access: that is, when the user needs to read and write data on the computer, then the data is read or written at the time or The locations are random and not fixed. In actual computer work, random access memory is mostly used to store operating system and various application data, etc.;

3. Easy to lose: This is also the biggest weakness of random access memory, that is, when the computer RAM cannot retain data after power is turned off. The power shutdown mentioned here refers to the phenomenon of sudden power outage of the computer under non-human operation conditions. If the user wants to save some data on the computer for a long time, he must use the computer's hard disk instead of the random access memory that is prone to data loss. The biggest advantage of rom storage, which is opposite to ram storage, is that the data on rom will not be lost after a power outage. This is also the biggest difference between ram and rom;
