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: in 2019, the global semiconductor market was worth 406.59 billion U.S. dollars, and my country's semiconductor market was about 140 billion U.S. dollars, accounting for more than 34%.

　　Memory chips are the most important segment of the semiconductor market. The demand for server data storage has expanded with technological progress, and the corresponding storage chip market has steadily increased. According to WSTS data, by 2023, the global memory chip market is expected to reach 1.12 trillion, with a compound growth rate of 5% in 2019-2023. China's memory chip market is 649 billion, with a compound growth rate of 6% in 2019-2023, and China accounts for nearly 60% of the global share.

　　As a global manufacturing base for electronic products, China has long been the largest demand market for memory products, but the rate of self-manufacturing of domestic memory chips is low, and there is a huge room for domestic substitution.
