What are the differences between a static RAM and a dynamic RAM?

In today’s article we will talk about What are the characteristics and differences between a static RAM and dynamic RAM? First of all, we must know  what is a RAM memory? RAM memory is an acronym that stands for Random Access Memory or in Spanish random access memory.

This memory is hardware that is in all computers, in which information is stored temporarily , making the computer work with a variety of information at the same time, making it perform well. It should be noted that when you turn off the computer, all the information stored in the RAM memory disappears.

RAM memory is one of the most important components in an electronic device and has been in use since 1969. With RAM, computers are faster when executing an action, storing data necessary for the use of an application, which at the end it delivers the information to be processed to the data processor.

We can say that RAM serves as an intermediate point for information, processing and storing data without following a pattern, making it easier to access it, working in a better way. With this contextualization of what a RAM is, we can fully enter today’s topic. We will see the characteristics that these two types of RAM memories have, to finally see the differences they have between them. We will mention and explain each of these points.

Characteristics of a static and a dynamic RAM

In the way of working, RAM memories can be divided into two types, being static or dynamic RAM memories. Each offers certain peculiarities, they bring pros and cons , and even can be manipulated by software to be released from load and work faster . For this reason, we will talk about these two types of RAM memories, explaining each of these, observing the positive and not so positive aspects that each of these offers us.

Characteristics of a static RAM

The first type of RAM that we will talk about is static RAM. The main factor that characterizes a static RAM memory is that it has its bases on a bistable circuit, having four or six transistors which are in charge of controlling the flow of electrical energy. Another of its main characteristics is the fact that it does not need to be updated, because the information is retained in this memory until it is overwritten.

This type of RAM memory has the advantage of being fast, being used in the parts of the memory where a more immediate data load is needed. The only disadvantage of using static memory is that this memory takes up more space on the memory chip, making static RAM more expensive than dynamic RAM.

Characteristics of a dynamic RAM memory

The second way in which RAM memories can be divided is dynamic RAM, which is more easily formed with just a transistor together with a capacitor . Dynamic RAM memories can be repeatedly updated if the information will be retained for a large amount of time.

Although they require less space than static RAM, they are less fast, but it makes them more affordable , helping to save money for those who do not need more speed. Precisely because of their economy they are more common in most computers.

What are the differences between a static RAM and a dynamic RAM?

Having the characteristics of each of these types of RAM, we are asked the question: What difference do they have? So we can answer it easily in three points, which is where the difference is most noticeable for us as users.

  • The first aspect where they differ is in their price, the static RAM being the higher cost while the dynamic RAM is lower in price .
  • On the other hand, the static RAM offers us more speed, the dynamic being the least fast.
  • Finally, in its use , dynamic RAM memories are more common, while static ones are used in special contexts.

We hope this article has been useful to you, giving you better criteria when purchasing one of these two types of RAM. Of the most efficient RAM memories are the Corsair Vengeance RGB Pro .
