How does the chip store information, and why can the chip store so much information?

The principle of chip storage information is as follows:

When writing to dynamic memory, the row address first latches RAS in the chip, and then the column address latches Cas in the chip, WE is valid, and the written data is stored in the specified cell.

When reading out the dynamic memory, the CPU first outputs the RAS latch signal to obtain the row address of the data storage unit, and then outputs the Cas latch signal to obtain the column address of the data storage unit, and keeps We=1 to read out the data in the memory cell with known row and column addresses.

The storage of information is the process of digitizing information, after the digitization of information is composed of 0 and 1, semiconductor storage medium you can see him as a very large number of diodes, the conductive characteristics of the diode are positive voltage conduction, negative voltage resistance is very large, conductive we record him as 1, open circuit is 0, he is not a molecular change, that is to say, it is not a chemical reaction, writing is the process of digitizing abstract information, for example, an image, you can imagine it as countless light and dark dots, 0 is dark, 1 is bright, then the graph is digitized according to a certain law, and then these 0s and 1s are put into the storage medium according to the law, which is the writing of numbers. Propagation is the conversion of information into electrical signals, electromagnetic waves are equal to the signal, electrical signals are expressed by the level of potential, and electromagnetic waves seem to be expressed by wavelength and frequency. The simplest magnetic storage medium is the magnetic tape, through the magnetic strength on the tape, the magnetic head will have a change in magnetic flux when sweeping the tape, it will produce a current of different strengths, and then the sound will be emitted through the current, the principle of the image is the same, but I don't know how it is made.

The chip cannot store information, and the information can only be stored temporarily. The essence of a chip is an integrated circuit, which is used for computing.

The principle of disk storage information is that molecularly equivalent magnets, and different arrangements represent different information, which can be stored for a long time.

The memory, as mentioned upstairs, is capacitors. The storage time is a little longer, but it is generally released after the program is over, not to mention the power failure, it is definitely gone.

High-speed propagation is actually the speed of electricity and electromagnetic waves, and the speed at which electric currents and electromagnetic waves transmit information is the speed of light. However, the electric current itself moves very slowly.

There are many kinds, not to mention the magnetic medium.

In general, integrated circuits use registers to store data, which is actually a bistable circuit. As for memory, capacitors are generally used.

It's not that I don't want to talk about it, the main thing is that I don't know what your foundation is, and I don't know how much you've learned, I've only learned for 20 years, so if you're interested, you can ask me.

The chip is able to store so much information mainly because it uses miniaturization technology and semiconductor technology.

On the chip, the information is stored in the form of binary **, each of which represents a number or character. Miniaturization technology makes the memory cells on the chip very small, allowing a large amount of binary** to be stored in a tiny space. For example, a modern chip may have billions of transistors, each of which can store a binary**.

Semiconductor technology is a key technology for chips to realize information storage and processing. Semiconductor materials have the ability to conduct electrons, which can control the flow of electrons. Both the memory unit and the processing unit in the chip are made based on semiconductor materials, and the information is stored and processed by changing the state of the charge.

As a result, the chip is able to efficiently store and process a large amount of information about the defeat of the company.

In addition, a variety of advanced technologies are also used in the design and manufacturing process of chips, such as lithography technology, thin film technology, polysilicon technology, etc. The continuous development and progress of these technologies also provide more support for the information storage capacity of the chip.

The chip uses the following working principle to store the program:

A chip is an integrated circuit that is made up of a large number of transistors. Different chips have different integration scales, ranging from hundreds of millions; As small as a few.

10. Hundreds of transistors.

Transistors have two states, on and off, which are represented by .

Multiple transistors produce multiple 1 and 0 signals that are programmed to specific functions (i.e., instructions and data) to represent or process letters, numbers, colors, graphics, etc.

After the chip is powered on, a startup instruction is first generated to start the chip, and then it continuously accepts new instructions and data to complete the function.
