Random Access Memory is a temporary based internal memory RAM Chip of your computer, as well as RAM is mostly using in all computing devices.
Functions of RAM in Computer
RAM (Random Access Memory) plays the role as temporary storage of data and program instructions which are access fastest by the CPU, when it needed.
Now, we will explain the primary functions of RAM (Random Access Memory) in laptop and mobile.
Reading Files: This is the basic function that performed by RAM. Your computer system contains the hard drive that helps to store massive data and cause delay functioning. RAM becomes difficult task to access any file from hard drive a file and programs stored on the hard drive remains scattered and to different types of zones.
To retrieve these types of files, HDD needs to move its mechanical read/write arm back and forth, when need to wait until its spinning patters spin into accurate position. Hard drive spin at the fastest speed but it delay while reading the files.
Due to this process, your system gets slowdown, so RAM allows storing all file and programs at once to read from HDD side. RAM does not contain any movable parts and it works at the higher speed thus it install all information quickly while using it.
Temporary Storage: Temporary storage is second function of RAM that allows temporary storage of all data on the RAM (Random Access Memory). When it uses all programs or files. RAM is capable to store information or data which programs are actively.
When your system keeps temporary data on RAM to run it temporarily it allows the system to work fast and efficient, and it helps to boost up the speed and performance significantly. You have option to enhance the RAM space as per system configuration for yielding excellent result.
Architecture of RAM
In RAM, memory cells help to access all information. And, it can be moving from one location to other locations randomly in your system. The process of identifying the word in the memory is same, and needs as same amount of time no matter that where cells are located in the physical memory.

The communication in between various peripherals and RAM (Random Access Memory) is done through input and output lines. And, control lines help to specify the path of transfer, and selection lines address.
Block Diagram of RAM
The n data input lines deliver the all information which hold in the memory, and n data output lines transfer the information that is to come out of specific word selected in the among of 2 (Power is K) available internally in the memory. Other two control inputs identify the path of transfer as per the need.
How Does RAM Work
Random Access Memory (RAM) is capable to perform two operations like as Read and Write. Read means signal transferring out, and Write means signal transferring in. Ram permits one of these control signals, internal circuit that embedded into inside memory. Then, they will deliver the required function, which expected from the user side.
- Supply binary address of the required word inside the address lines.
- Supply the data bits which are must hold into memory internal of data input lines.
- To be activated write input.
To move out the stored word out of memory unit the following occurs:
- Binary address of the needed word supplied into the address lines.
- To be activated read input.
