In this issue, the editor will bring you what it means to install memory. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

RAM (random access memory) RAM-random access memory random access memory.

The contents of the memory unit can be taken out or stored at will, and the speed of access is independent of the location of the memory unit. This kind of memory will lose its storage content when the power is off, so it is mainly used to store programs used for a short time. According to the different storage information, random access memory is divided into static random access memory (Static RAM,SRAM) and dynamic random access memory (Dynamic RAM,DRAM).

Extended data:

The storage matrix of dynamic RAM consists of dynamic MOS memory cells. The dynamic MOS memory cell uses the gate capacitance of the MOS transistor to store information, but because the capacity of the gate capacitance is very small, and the leakage current can not be absolutely equal to 0, so the charge storage time is limited. In order to avoid the loss of stored information, the missing charge must be replenished to the capacitor regularly.

This operation is usually called "refresh" or "regeneration", so there is a refresh control circuit inside the DRAM, and its operation is more complex than the static RAM. However, DRAM memory cell has become the mainstream product of high-capacity RAM because of its simple structure, few components and low power consumption.

The above is the meaning of the installation memory shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
