Volatile Memory vs. Non-Volatile Memory: Key Differences

You may be familiar with the memory of your computers but may not be aware that they are categorized into two parts -volatile memory and non-volatile memory. They are amazing innovations that work hand-in-hand to bring you the best service that a computer can offer. They have their functions and features. They also have key differences that make the volatile memory and non-volatile memory unique. You need to read more to find out what they are and how they are used in our everyday lives. 

Differences Between Volatile and Non-volatile Memory

Volatile memory definition

Volatile memory is also known as dynamic memory or temporary memory. It is called as such because it is a type of memory that only stores data as long as power is supplied to it. When the power is pulled out, it no longer keeps the data that it has. A typical example of volatile memory is random access memory, often referred to as RAM. You may have noticed that RAM works as part of the Central Processing Unit of your computer and becomes part of the overall functionality of these machines when it is running programs and apps. 

Non-volatile memory definition

On the other hand, non-volatile memory is also popularly known as permanent memory or static memory. This is the hardware that is commonly used to store all your computer data. It does not need power to sustain and keep the files that it stored. The challenge with non-volatile memory is its ability to transfer and move data inside the computer. It takes longer to do it compared to volatile memory. This is the main reason why it takes time for computers to load stored files and even transfer them from one storage to another. The cost of making non-volatile memory is cheaper compared to volatile memory. 

Data stored 

Volatile memory works directly with the CPU as it stores the data in real time. Since it deals more with running programs and apps, the volatile memory needs to move and transfer files quickly. Non-volatile memory can store data through the use of a Basic Input and Output System. This means that it can retain the amount of files in its storage for long periods or even permanently. Both are useful in terms of the overall process of a computer. 

Position of memory

Volatile memory chips are often found stored in memory slots. You can find computers that have more than one slot. This means that you can add more RAM to your computer so that performance will be better and faster compared to a smaller RAM size. Non-volatile memory chips are installed and embedded in the motherboard of the computer. If you want to increase the size of the memory of the computer, you can buy external drives which you can plug into it for extended storage. This will serve as additional space for all your files to be saved. 

Conclusion

They are not two different entities but two sides of the same coin. You need one for the other to flourish. The primary storage or volatile memory is used to make the processing fast and reliable. You need the volatile memory so that programs will run quickly and efficiently with little or no delay. On the other hand, the computer needs secondary storage to keep the files even if no power is supplied to the computer. They are very useful technology that made computers what they are today. As they continue to improve, you can expect both the volatile and non-volatile memory to be better than ever in terms of performance and reliability.
