Defination Of Computer Memory :

A Computer Memory is comparable to a human’s brain. Not only does it store data and information, but it also stores commands. Whether it’s a data storage unit or device, it serves as a repository for both the instructions required for data processing and the data itself. This location is capable of storing both the input and the output of the system.

How Does Computer Memory Work?

Every time you open a program, it loads from secondary memory into main memory. The transfer of a program from a solid-state drive (SSD) to random-access memory (RAM) is an example of the many different forms of memory and storage that are available.

The opened program is able to establish a connection with the computer’s CPU in a more expedient manner due to the fact that main storage is accessible more rapidly. Because it is easily accessible via temporary memory slots or other storage locations, the main memory is readily available.

Computer Memory, being a volatile medium, only stores information for a brief duration. If a computer device switches off, its volatile memory immediately deletes the stored information. When we save a file, we transfer it to secondary memory for storage.

One can access a wide variety of memory types. The function of the main memory ultimately depends on its type. On the other hand, semiconductor-based memory is frequently associated with large memory. Integrated circuits (ICs) that are composed of silicon-based metal-oxide-semiconductor (MOS) transistors are the components that make up semiconductor memory.

Types of Computer Memory

  • Primary Memory
  • Secondary Memory
  • Cache Memory

Computer Memory

Primary Memory :

We also refer to it as the computer system’s primary memory. The computer uses it to store data, programs, and written instructions during its functioning. Because it relies on semiconductor technology, we typically refer to it as semiconductor memory. There are two categories of primary memory:

  • RAM (Random Access Memory)
  • ROM (Read Only Memory)

Secondary Memory :

Auxiliary memory and backup memory are two additional names for this type of memory. To store a significant quantity of data or information, it is a kind of memory that does not lose its contents over time. While secondary memory operates at a slower pace than main memory, it permanently stores data or information. It is not possible for a central processing unit to directly access secondary memory. The central processing unit (CPU) must first transfer the data or information from the auxiliary memory to the main memory before it can retrieve it. Secondary memory are three types:

  • Magnetic Tapes
  • Magnetic Disks
  • Optical Disks
Cache Memory :

The central processing unit (CPU) may benefit from the use of this form of high-speed semiconductor memory. It is useful for storing the data and applications that the central processing unit (CPU) utilizes the most often.
