Here I am going to discuss the explanation of RAM in detail as we all know that it stands for Random access memory. This is a type of computer memory that can be changed and read in any order. It is computer hardware, RAM is the main memory in a computer and is versatile in nature. It is volatile in behaviour it means that the data will remain in the storage until the computer will be on. If the laptop or the computer will be shut down then the data will be lost. When the computer is rebooted then the Operating system and the other files are reloaded into the RAM. This is usually from the (HDD) Hard disk and solid-state drive.

How does RAM work?

This is the main interesting thing that you are waiting to know that how does a RAM work. Now I am going to explain all these in a simple way. As we know that full form of RAM is random access memory. The random access memory. I will explain it term wise, start from the “random access” This term refers to any storage and locations. It s also known as a memory address. This term was used to distinguish regular core memory from offline memory.

How much RAM is good for you?

It is just like the amount of money you have in your pocket in response to that you will invest. In the same manner amount of RAM depends upon your need. If you will have good RAM then you can perform different actions on your computer. If you want to edit videos on your computer then you need at least 16 GB RAM. You want to play games and perform activities such as photoshop then you can use RAM up to 8 GB. So basically RAM depends upon the type of work that you perform on your computer.

Types of RAM

Now I am going to mention the types of RAM. Basically there are two types of RAM. It plays an important role in the explanation of the RAM.

  1. DRAM (Dynamic random access memory)- It usually makes up the competing device RAM. As I have mentioned earlier that earlier, it needs that power to be on to retain stored data. There is an electrical capacitor in the RAM. There is an availability of an electrical capacitor that holds the lack of charge of the DRAM cell. This data must be refreshed with the charge. Moreover the transistor work as a gate that determines whether the capacitor value will be written or read.
  2. SRAM (Static Random Access Memory ) It also needs a power supply to hold the data but it doesn’t like the DRAM where you had to continuously refresh the data. In SAM, the transistor acts as a switch, with one position serving as 1 and the other position as 0. Static RAM requires several transistors to retain one bit of data. SRAM is better than the DRAM because it uses less power and is also more effective. Its chips are much larger and more costly than the DRAM.

There are some other types of RAM, that comes under the explanation of RAM. that I am going t mention you below.

  1. SDRAM– It stands for Synchronous Dynamic Random Access Memory. The word synchronous tells us about the behaviour of the DRAM type. SDRAM began to appear in the system in late 1996. It is different from the previous technology it synchronises with the limit of the CPU. This enables the memory controller to know the request and the requested data will be ready. So now the CPU will not have to wait to access the memory. In this way, your computer will become fast. This can also be defined as the single data rate SDRAM. It means that it can be read/write one time in a clock cycle. It will have to wait until the previous command is completed.
  2. DDR SDRAM – It stands for DDR SDRAM (Double Data Rate SDRAM). It is also known as the next generation of SDRAM. It doubles the transfer rate without increasing the frequency of the clock. The approx transfer rate of the DDR is about  266~400 MT/s. DDR266 and DDR400. It has good bandwidth so that the transfer of the data per clock is high. Without changing the internal clock the transfer rate of DDR is doubled from the SDR RAM.
  3. DDR2 SDRAM– It stands for (Double Data Rate Two SDRAM) The main benefit of the DDR2 SDRAM is that it has the operate the external data bus twice as fast as DDR SDRAM. This is approved by just approving the bus signals. The transfer rate of the DDR2 is 533~800 MT/s. It can be done only with the improved I/O bus signal. DDR2 533 and DDR2 800 these two types of memories are available in the market.
  4. DDR3 SDRAM– It stands for (Double Data Rate Three SDRAM) It reduces the 40% power consumption as compared to the DDR2. It functions on the lower operating. The transfer rate of DDR3 is 800~1600 MT/s. There are two additional functions in the DDR3, ASR (Automatic Self-Refresh) and SRT (self-refresh Temperature). They can control the memory according to the temperature variations.
  5. DDR4 SDRAM– It stands for (Double Data Rate Fourth SDRAM) The main feature about this RAM is that it provides a lower operating voltage (1.2V) and higher transfer rate. The actual transfer rate of the DDR4 IS ABOUT 2133~3200 MT/s. It comes with the four bank groups technology. it has the features of single-handed operations. It is much faster as it can process 4 data within the one clock cycle. There are some of the additional functions such as DBI (Data Bus Inversion), CRC (Cyclic Redundancy Check) and CA parity. It enhances signal integrity and hence it improves the stability of data access.

Basically these are some of the types of RAM. I have tried my level best to give an explanation of RAM, So that you may decide the best RAM for your computer.

MHz in RAM

MHz stands for megahertz. It is the measure of the speed of RAM is count. It is the measure of how many times per second the RAM can access its memory. This is the measure of the clock speed. The RAM frequency is measured in MHz. So we can say that if the RAM has good MHz frequency then it will be a typically faster computer.

Higher RAM means higher speed?

This is the main question that usually people ask. This is the main question that I am going to clear here. In simple words, the work of the Ram is to transfer the memory from one component to another component. If you will have faster RAM then your computer processing will also be faster. So these are some of the important things regarding the Ram. The speed of RAM is measured in Megahertz (MHz), millions of cycles per second so that it is compared to your processor’s clock speed.

 Now I think you are all clear about the RAM higher RAM and the speed of the computer. Basically it is a type of storage that is volatile in nature, The data is lost when the power is cut. It works until the power is supply is on. Once the power is cut the data will be lost. It will affect the speed of the computer, so if you need a higher speed computer then you will have to take a high-quality RAM such as 16 GB or more.


In this article I have mentioned about the explanation of RAM, Basically, this article covers the detailed information about the RAM. Here you are going to receive the types of RAM and the whole functioning of the RAM. Moreover, you will also know the MHz in the ram. How does RAM affect the functioning of the COMPUTER? These are some fo the detailed information that I have mentioned here. You can also choose the best RAM for you after this reading this article. You can purchase these RAM from here. Hope this was a helpful article for you.
