If you like computers, I’m sure you know what RAM is. You know that having a lot and quickly is the most important thing for your PC. RAM is one of the most important components of the computer.
Now, if they’re talking about DRAM and you need to look away, it’s super necessary that you start reading all you can about it.
What you will find here: What is DRAM? What is DRAM used for? Types of DRAM memory. Advantages of DRAM. Disadvantages of DRAM
What is DRAM?
Basically, DRAM is a specific type of RAM. DRAM stands for “Dynamic Random Access Memory”which means in spanish “Dynamic Random Access Memory”.
DRAM bases its operation on a transistor and a capacitor, components used to represent the bits.
These capacitors gradually lose their charge. To prevent completely lose chargethese memories use a very interesting method.
DRAM uses a dynamic refresh circuit that occasionally checks the circuit and resets any load on the next refresh cycle.
This methodology allows the memory to continue to retain its data.
If this cycle is not completed, the data is lost.
This is an opposite concept to that used in SRAM memories, that is to say static memories. These memories, as long as they continue to be fed, do not need to be refreshed.
As you know, All computers have RAM. but in most modern computers, the type of memory used in DRAM.
Do you want to know what all types of computer memory are? In this post you will know: Computer memory.
What is DRAM used for?
All types of memory perform the same function. Preserve the data so that the CPU can access it quickly. This is precisely the main function of RAM.
As you know, when you use your PC, programs need to be fed with data.
This data is processed by the CPU, so this information must be available as quickly as possible.
In that case, DRAM memory, like all other types of memory on the market, do the same job, but their technical differences. These operating differences for the user are not significant.
The only thing the user will notice is an improvement in performance.
Types of DRAM Memory
As mentioned, DRAM memory is a type of RAM. Now, in DRAM, there are subtypes that differ in certain technical aspects.
SDRAM memory
In this type of memory, the reading and writing of data must be synchronized by a clock. In SDRAM memory its pins are synchronized with the processor in order to improve performance.
DDR SDRAM memory
This type of memory offers the same SDRAM technical specifications. However, they can give up to twice the data transmission frequency. For this reason it is called “Double Data Rate SDRAM”.
ECC-DRAM memory
ECC DRAM is a type of RAM that contains a error correcting code (ECC), For this, they have an additional cell, which is used to detect damaged data and correct it, if possible.
DDR2, DDR3 and DDR4 memories
You could say that DDR memories have increased in speed and capacity with each generation. If you pay attention, each version of DDR memory is faster and more energy efficient than the last.

Advantages of DRAM
It is clear that DRAM memories offer a multitude of advantages, usable by any user.
- Increased operating speed: In general terms, DRAM is the fastest type of memory. East capable of recovering data from any storage unit quickly and without errors. After years of development, this type of memory has proven its effectiveness and safety. For this reason, they are the most widely used today.
- Increased storage density: One of the most important characteristics of DRAM is that it you can store more data per GB. than any other type of RAM. In some implementations, the limited amount of system RAM may be a problem and the DRAM density a solution.
- Lower cost: Compared to other types of memory, DRAM is much cheaper. This is due to its electronic design. And by becoming popular in the computer world, it is getting cheaper with each passing day.
Disadvantages of DRAM
Although DRAM memories offer a large number of advantages, the truth is that they have their questionable side. The most significant disadvantages of DRAM are:
- They consume more energy to operate: DRAM memory consumes more power than other memory types. This is due to the operating speed they achieve. If power consumption isn’t an issue for your implementation, it won’t be an issue. However, if you are at the limit of consumption, you will have to think of other types of memory.
- Volatility: Another disadvantage of DRAM memories is their volatility. Of course, this is a problem on all types of RAM. The only thing we can tell you about this is that don’t forget to save your documents from time to time!
- They become warmer than other memories: Obviously, by consuming more energy, DRAM gets hotter when running. If this is a problem with your computer’s space or layout, you can improve the cooling of your equipment. If this is not enough, it will be necessary to think of another type of memory.
