What is ferromagetic memories ?

I need matter on this help me please, searching so many webs can't get proper matter :(

 

[SteamKing]

Try googling 'core memory'

Are you asking about what people usually called "core memory"?

In short it is like this , you have a wire going through an ferromagnetic ring, you can have two poles , pass the current in one way and you have N S pass it the other way and you have S N ,So for a given input you have either one or the other output , now insert the binary code in all of this and you get either 0 or 1.
have many of these wires going through many rings and you have many ones and zeros and now you can compute some information. + you can store it because the ferromagnetic piece if not distracted will stay at it's last state for a while (keeping it's magnetic polarity) atleast some materials tend to do this.

Ferromagnetic memories are a type of computer memory that is based on the use of ferromagnetic materials, such as iron, cobalt, and nickel, to store and retrieve data. These materials have the ability to retain their magnetic properties even after the magnetic field is removed, making them ideal for use in memory storage devices.

Ferromagnetic memories work by using the magnetic polarity of the material to represent binary data, with one polarity representing a 0 and the other representing a 1. This data can be read and written by applying a magnetic field to the material.

One of the main advantages of ferromagnetic memories is their non-volatile nature, meaning they retain their data even when power is turned off. This makes them useful for applications that require long-term data storage, such as in hard drives and magnetic tapes.

In recent years, ferromagnetic memories have been replaced by more advanced technologies such as flash memory and solid-state drives. However, they are still used in some applications due to their low cost and reliability.
