Competitive landscape of the memory chip industry
Subdivided product competition pattern: DRAM and NANDFlash are the main products. From the perspective of memory chip segmentation products, DRAM and NANDFlash currently occupy more than 95% of the market share of memory chips. According to the data released by ICInsights, DRAM sales will account for about 53% of the entire storage market in 2020, and the proportion of flash memory will reach about 45%, of which NAND flash memory is 44%, NOR flash memory is 1%, and other memory chips (EEPROM, EPROM) , ROM, SRAM, etc.) will grow slowly, but it is likely to grab the market share

Memory chip: the most important segment of the semiconductor market
Memory chips are an indispensable key element in emerging fields such as the Internet of Things, big data, and cloud computing in the future. Therefore, the autonomous controllability of memory chips is of great strategic significance to the advancement of my country's new round of informatization. The implementation of the "National Integrated Circuit Industry Development Promotion Outline", "Manufacturing 2025" and other series of policies and the large fund-led capital investment have laid a good foundation for the accelerated development of the domestic memory industry. According to WSTS statistics, my country's semiconductor market is showing a rapid growth trend, and the growth rate of the semiconductor market is higher than that of the global market: the global semiconductor market in 2019 is 4.0

What is the working principle of the memory?
The memory is a memory component used to store programs and various data information. Memory can be divided into two categories: main memory (main memory or memory for short) and auxiliary memory (auxiliary memory or external memory for short). It is the main memory that directly exchanges information with the CPU. The working mode of the main memory is to store or read various types of information according to the address of the storage unit, collectively referred to as accessing the memory. The carrier that collects storage units in the main memory is called a memory bank. Each unit in the memory bank can store a string of information represented by a binary code. The total number of bits of this information is called the word length of a memory unit. There is a one-to-one correspondence between the address of the storage unit and the information stored in it, and the unit address is only
