What is memory?

Memory is one of the most important components in the computer. It is the bridge between the program and the CPU.

All programs in the computer run in the memory, so the memory has a great impact on the computer. The memory is also called the main memory. Its function is to store the calculation data in the CPU and exchange it with external storage devices such as hard disks. data.

As long as the computer is running, the CPU will transfer the data that needs to be calculated to the main memory for calculation. When the calculation is completed, the CPU will transmit the results. The operation of the main memory also determines the stable operation of the computer.

Physical structure of memory

The interior of memory is composed of various IC circuits. There are many types of memory, but it is mainly divided into three types of memory:

Random access memory (RAM): The most important type of memory, meaning that data can be read from and written to. When the machine is turned off, the information in memory is lost.

Read-only memory (ROM): ROM can generally only be used to read data and cannot write data, but when the machine loses power, the data will not be lost.

Cache: Cache is something we often see. It is divided into level one cache (L1 Cache), level two cache (L2 Cache), and level three cache (L3 Cache). It is located between the memory and the CPU. , is a memory that reads and writes faster than memory. When the CPU writes data to memory, the data is also written to the cache. When the CPU needs to read data, it will read it directly from the cache. Of course, if the required data is not in the cache, the CPU will read the data in the memory.

The memory IC is a complete structure. It also has power supply, address signals, data signals, control signals and IC pins for addressing to read and write data. Here is a virtual IC pin diagram:

In the picture, VCC and GND represent the power supply, A0 – A9 are the address signal pins, D0 – D7 represent the control signal, RD and WR are good control signals. I use different colors to distinguish them, and connect the power supply to VCC and GND, you can pass 0 and 1 signals to other pins. In most cases, +5V means 1, and 0V means 0.

We all know that memory is used to store data, so how much data can be stored in this memory IC? D0 – D7 represent data signals, that is to say, 8 bit = 1 byte of data can be input and output at one time. A0 – A9 are ten address signals in total, which means that 00000 00000 – 11111 11111 can be specified, a total of 2 to the 10th power = 1024 addresses.

Each address stores 1 byte of data, so we can conclude that the capacity of the memory IC is 1 KB.

Memory reading and writing process

Let us focus on the process of reading and writing data by the memory IC! Let’s look at a model for writing and reading data to a memory IC

What is PNG memory ic used for?

How about PNG memory stick?

PNG memory sticks refer to memory sticks using the PNG (Portable Network Graphics) format. However, in current computer hardware, PNG format memory sticks are not used because PNG is an image file format, not a hardware device for storing data.

The memory stick in a computer usually refers to RAM (Random Access Memory), which is a temporary memory in the computer used to store running programs and data. RAM formats and standards are dictated by the computer hardware industry, not image file formats.

Therefore, the issue of “PNG memory stick” is actually a misunderstanding or confusion. PNG is just an image file format, and it is two completely different concepts from the computer’s memory stick. Therefore, it is impossible to make a specific evaluation or comparison of the “PNG memory module” because it is not an actual hardware device.

3. Security: The PNG format supports transparency and alpha channels, allowing you to create images with complex backgrounds and transparency. This makes PNG memory ICs somewhat secure when storing and transmitting sensitive data, as data visualization and access rights can be better controlled.
4. Efficiency: PNG is an efficient image file format that can reduce file size and storage space while ensuring image quality. This makes the PNG memory IC more efficient when storing large amounts of image data, saving storage resources and transmission costs.

It should be noted that the above advantages are only some possible aspects, and the specific advantages depend on the actual application scenarios and needs.

What are the disadvantages of PNG memory ICs?

Disadvantages of PNG memory ICs may include the following:

1. Compatibility issues: Although PNG is a widely used image file format, there may be compatibility issues in some specific fields or software. For example, some older software or operating systems may not be able to correctly recognize or open PNG files.
2. Insufficient animation support: The PNG format does not support animation effects. Compared with other dynamic image formats (such as GIF or MP4), it has limitations in expressing dynamic content.
3. Relatively large file size: Compared with some other image formats (such as JPEG), the file size of the PNG format is usually larger, which may affect storage space usage and transmission efficiency.
4. Transparency problem: Although PNG supports transparency settings, in some cases there may be problems with improper transparency processing or transparency not matching the background, which may affect the overall effect of the image.

It should be noted that the above disadvantages are only some possible aspects, and the specific disadvantages depend on the actual application scenarios and requirements. When choosing to use a PNG memory IC, you need to weigh its advantages and disadvantages based on actual needs.

Thick film integrated circuits refer to the integration of circuit components and wires on ceramics or other insulating materials, and are usually used to manufacture medium- and small-scale integrated circuits.

Working principle

The working principle of memory integrated circuits is mainly to store and read data through the switching characteristics of semiconductors. In volatile memory, each memory cell usually consists of a transistor and a small capacitor. The source and drain of the transistor are connected together as the input/output terminal of the memory cell. One end of the small capacitor is connected to the gate of the transistor, and the other end is connected to ground. When a small capacitor is charged, the threshold voltage of the transistor changes, causing the transistor to be in different switching states to enable data writing. When reading data, it is determined whether the data stored in the memory cell is 0 or 1 by reading the switching state of the transistor.

In non-volatile memory, each memory cell usually consists of a floating-gate transistor. Floating-gate transistors have a polysilicon gate that stores electrons. When electrons enter the floating gate, the threshold voltage of the transistor changes, allowing data to be written. When reading data, it is determined whether the data stored in the memory cell is 0 or 1 by reading the switching state of the transistor.

How does the power module in the embedded driver be designed with the power module

In the cooling design of the power module in the embedded drive, the main consider how to effectively export the heat from the power module and reduce its working temperature to ensure the stable operation of the power module and extend its service life. Here are some points of some cooling design:

2. Natural cooling or forced cooling: According to the heat dissipation needs of the power module, you can choose natural cooling or forced cooling method. Natural cooling mainly relies on the natural flow of air to dissipate heat, which is suitable for lower thermal density. For compulsory cooling, it is necessary to use a fan or other forced ventilation equipment to be suitable for high -heat flow density.
3. The radiator design: If you need to use a radiator, you should choose the appropriate material (such as copper or aluminum) and shape to effectively export the heat from the power module. At the same time, the surface area of the radiator should be large enough to quickly emit calories.
4. Heating material: The heat conduction material (such as thermal grease or thermal pad) should be used between the power module and the radiator to transmit the heat from the power module to the radiator.
5. Isolation and protection: In order to prevent dust and other impurities from affecting the heat dissipation effect, appropriate protection and isolation measures should be set around the power module.
6. Monitoring and control: You can install the temperature sensor to monitor the working temperature of the power module, and use the control circuit to adjust the working state of the power module to maintain it within the appropriate temperature range.
7. Consider cost and space limit: In the design of heat dissipation, cost and space restrictions should be considered. Select the appropriate heat dissipation solution to meet the heat dissipation needs of the power module, and also consider the cost and size requirements of the product.

In short, in the cooling design of the power module in the embedded drive, multiple factors need to be comprehensively considered, such as heat sources, heat dissipation methods, heat sink design, heat conduction materials, protection measures, cost and space restrictions. Through a reasonable heat dissipation design, the working temperature of the power module can be effectively reduced to ensure its stable operation and extend its service life.

2. Efficiency: The efficiency of the switching power module is usually high, which can reach more than 80%of the energy conversion efficiency, and the efficiency of linear power modules is relatively low, generally between 50%and 60%.
3. Volume and weight: Because the switching power module uses a high -frequency switch to switch to achieve voltage conversion, its components can complete the voltage conversion in a smaller space, so the volume is small and the weight is relatively light. The linear power module needs to use large coil transformers and radiator components, and the volume and weight are relatively large.
4. Cost: Generally, the manufacturing cost of switching power modules is relatively low because they use less materials and components. The manufacturing cost of linear power modules is relatively high because more coil transformers and larger radiators need to be used.
5. Stability: Linear power modules usually have lower noise and good stability, and can provide clean output power. The switching power module may produce some electromagnetic interference and noise due to high -frequency switching.

In summary, linear power modules and switching power modules have their own advantages and disadvantages in terms of efficiency, volume, weight, cost, and stability. In practical applications, you can choose the appropriate power module type according to the needs.
