10 Types of RAM Laptops and PC Computers – Random access memory or RAM is a computer device that functions as memory or data storage. However, RAM functions as memory or temporary data storage.

10 Types of RAM Laptops and PC Computers
Thus, RAM only works when the device, be it a computer or laptop, is on. The performance of this device really affects the performance of a computer or laptop. The greater the RAM capacity, the faster the performance of your laptop or computer.

However, did you know that RAM actually has many types? Well, in this article, we will explain several types of RAM that can actually installed on your laptop or computer.


Types of Laptop and PC RAM



Dynamic random access memory or often abbreviated as DRAM is the type of RAM that is most often use in computers or laptops. This type is a semiconductor memory that serves to store data and program code on the computer processor.

Semiconductor memory means this type requires a capacitor to refresh the data in the computer. The advantage of DRAM itself is that it has a simple design, but its speed is quite high. The average speed of DRAM is around 4.7MHz to 40MHz.



Synchronous dynamic random access memory or SDRAM is a form of development of DRAM. However, the heyday of SDRAM only occurred at the end of 1995 to 2003. However, SDRAM can be said to have a capable speed.

Noted, SDRAM has a speed between 100MHz to 133 MHz. In addition, the capacity of the SDRAM itself reaches 16MB to 1GB.



Rambus dynamic random access memory or RDRAM is still include in the development of this type of DRAM. RDRAM has a super fast speed compared to RAM at its time. Released in mid 1995 to 1996, the speed of RDRAM has reached 1GHz.

That level of speed makes RDRAM unable to be installed on all types of motherboards. RDRAM is only suitable for server-class computers or computers used for video graphics accelerators.



SRAM stands for static random access memory. As the name implies, this type of memory is static or does not need to be refreshed periodically. SRAM is a semiconductor, but does not require capacitors like DRAM.

This arrangement makes SRAM has a higher speed than DRAM. However, the memory capacity provide by SRAM is very limited. However, with its speed and composition, SRAM usually costs more than DRAM.



Extended data output random access memory or EDORAM is a type of RAM that was release in 1994. This type has a faster speed than RAM in general at that time. However, that only happens when EDORAM uses L2 Cache. EDORAM will turn very slow if you don’t use L2 cache.

In addition, EDORAM is design to a temporary memory for Intel’s Pentium processors. This type of RAM has a 72 pin memory slot.



FPM DRAM is an early form before the development of the latest version of DRAM. This memory which stands for first page mode DRAM has a fairly high speed when using L2 cache. The maximum transfer speed of FPM DRAM when using L2 cache can reach 176MBps.

FPM DRAM was the most widely and commonly used type of memory in computers prior to the release of the latest version of DRAM.


Flash RAM

Flash RAM actually has another name, namely non-volatile RAM. This type is unique compare to the previously mentioned types of RAM. Flash RAM can used to write and delete data.

In addition, Flash RAM can also still store incoming data, even if there is no power connected to it. This type of memory is usually found in USB flash drives, children’s toys, printers, and televisions.



SDR SDRAM is actually often known as SDRAM only. SDR itself stands for single data rate. That means this type of RAM is only able to send one instruction to the processor in the CPU in one clock cycle.

Besides being use on computers, SDRAM is also use in other devices, such as video game consoles that you often play.



Over time, SDR SDRAM has developed with the emergence of DDR SDRAM. DDR itself stands for double data rate. This means that this DDR SDRAM has a performance that is twice as good as the SDR type.

DDR can send two instructions in one clock site to your computer’s CPU. In addition, DDR is also experiencing development, starting from DDR1, DDR2, DDR3 and DDR4. However, until now, the most popular DDR SDRAM is DDR3 because the price is affordable and the speed is quite high.

GDDR SDRAM is arguably still related to DDR SDRAM. However, GDDR is use on video cards that function to process graphics and video. As such, GDDR is usually use in the rendering process of videographers.

GDDR has a slight difference in terms of capabilities when compared to regular DDR. This type is able to request and receive data at once only in one clock site. This makes GDDR able to use less power than DDR.


The final word


Well, those were the various types of RAM that you should know and you can use in your computer or laptop. As much as possible, adjust to the needs of your computer and laptop. May be useful!
