What is RAM?

Many may be interested in the question of what is RAM. You can talk about this. RAM is a part of the memory system that the processor has the ability to access in one operation. It focuses on the temporary storage of commands and data that the processor needs to carry out operations. Many may also be interested in why RAM is needed. It directly transfers data to the processor. Each RAM cell has its own address. Modern computing devices use memory, arranged according to a new principle, according to dynamic technology with random access. This concept assumes that the current memory access does not take into account the order of previous operations, as well as the location of data in memory. RAM can be made as a separate unit or be an integral part of a single-chip computer.

Understanding the question of what RAM is, it is worth saying that the data contained in it is available only when voltage is applied to it, that is, when the computer is turned on. The lack of voltage on the memory modules leads to a complete loss of information on RAM or its distortion. RAM is a storage of data of the operating system and programs launched for execution, so the number of tasks that can be performed simultaneously depends on its quantity. The most common amount of RAM at the moment is from 1 to 4 gigabytes, which can be on one or more slats. The most popular manufacturers are Transcend, Samsung, Kingston.

So, understanding what RAM is, it's worth talking about dynamic RAM. This type is used in most modern systems. Its main advantage is that the cells are very densely packed, that is, a lot of bits fit on a small microcircuit, and this allows you to create memory of significant capacity. When starting computer programs, files are downloaded to RAM, where they are in the process of working with the application. The processor executes instructions, the results of which are also stored in RAM. In the process of working with a text editor , the codes of the pressed keys are stored in memory, and when you click "Save", the contents of the RAM are saved on the hard drive as a file.

As memory cells in the chip are capacitors that hold charges. This type of memory is associated with problems regarding its dynamism, that is, its constant regeneration, as otherwise data may be lost. The regeneration process loads the processor, because each cycle of this procedure takes several of its cycles. Older computers used up to 10% of the processor time to regenerate, but modern systems spend less than 1%. Dynamic memory devices use one transistor to store one bit, so they are more capacious than other types of microcircuits.

Now we can say about random access memory. This type of memory allows you to write or read data at any time. It can be dynamic or static. Static RAM are represented by triggers as storage elements, which allows reading without loss of information. Dynamic memory uses capacity as a storage element, and this requires the restoration of information during its storage and subsequent use. Modern dynamic RAMs are equipped with regeneration and synchronization mechanisms, so they do not differ from static ones in external signals.

So, you should understand what RAM is.
