The random access memory , or RAM , is the physical hardware that can be found inside a computer whose function is to store data temporarily serving as memory ” operational “ computer. The additional RAM allows a computer to work with more information at the same time, which generally has a dramatic effect on the overall performance of the system. Some of the popular RAM manufacturers include Kingston, PNY, Crucial Technology, and Corsair.

What is RAM memory?

RAM is the most important memory in a device and is the place where  all programs and informational data are (temporarily) stored . It is random access memory.

RAM memory features

The main characteristics of RAM are:

  • The times when the information is in the modules is quite short.
  • If there is a cut of electricity information tends to disappear.
  • It is the most important component of the computer.
  • It processes the information that the main processor needs .
  • It is also called random access because it can be written and read without following a specific pattern.


The parts of RAM are:

  • Board : is a circuit board on which the hardware elements are soldered.
  • Clock : operations are synchronized by the clock which helps to simplify the control interface and eliminates pseudo-analog signals.
  • Record mode : controls the duration and type of columns.
  • Memory banks : contains the cells that store the information.
  • SPD chip : contains information about memory, size, speed and access.
  • Burst counter : its function is to facilitate queues to improve access.
  • The speed with which information is transmitted is measured by means of Mega Hertz or Giga Hertz .
  • RAM memory can be expanded by adding another memory to the computer.
  • The normal capacity of the RAM can be 4 Gb , 8 Gb and 16 Gb .
  • There are different speeds of RAM memories: between 66 and 133 MHZ, between 200 and 600 MHZ, between 400 and 800 MHZ, between 600 and 1066 MHZ and those that transmit more than 2,000,000 data per second.

What is RAM memory for?

It is useful to us because it improves the response speed of the equipment when a program is used on the computer since the information that the program needs to function is stored in RAM memory.

When the program is executed, the instructions to be executed are passed to the processor making data transmissions as needed. RAM memory is responsible for storing said information and sending the data to be processed to the processor .


The first RAM memory was called magnetic core memory , and it was created between 1949 and 1952, it was used in many computers until integrated circuits emerged in the late 60s and early 70s. Before that, computers used relays and delay lines to perform main memory functions with or without random access .

In 1969, the first silicon semiconductor RAM memories created by Intel emerged, and the following year a 1024-byte DRAM memory was introduced , marking the beginning of the end for magnetic-core memories .

In 1973 the time multiplexing of memory addresses emerged. MOSTEK released the 4096-byte MK4096 reference in 16-pin packaging. At the end of the 70’s the integrated ones were used in most of the new computers. Over time the first memory modules such as SIPP were created .

How RAM works

The RAM memory works as a kind of intermediary of information that occurs in the storage media and is in charge of processing it. When the CPU has to reach the data that is stored inside the hard disk to be able to execute a task, it extracts it from the RAM memory, otherwise it would take a long time. The information loaded from RAM is easier to access and works better.


There are several types of RAM memory that are described below:

  • DDR or SDRAM : it is a dynamic memory that intertwines two or more internal memory arrays in such a way that while a matrix is ​​being accessed and that allows data to be read and written at 2 times the buz speed.
  • DDR2 : are an enhancement to DDR memory that allows input buffers.
  • DDR3 : It can become 2x faster than DRR2 memory, and it can transfer data at an effective clock rate of 800-2600MHZ.
  • The cache memory or RAM cache: it  is a special high-speed storage system, and it is a part of high static RAM used as main memory.  Caching is effective because programs access the same data and instructions over and over again .


The amount of data that manages to enter the RAM is what we know as its capacity. If there is not enough capacity, many of the applications will not be able to function. The memory capacity must be bytes , megabytes or gigabytes and is expressed in mega Hertz or giga Hertz .
