Memory chips of hard drives are widely used in memory

As one of the three major categories of integrated circuits, memory chips are widely used in memory, consumer electronics, smart terminals and solid-state storage hard drives. Their sales account for more than 25% of the entire chip industry, reflecting the status of a country or region. The level of semiconductor development. According to CCID Consultings data, the storage chip market reached 246.55 billion yuan in 2014, accounting for 23.7% of the integrated circuit market. However, the memory chip basically relies on imports, and the amount of imported memory chips is as high as 60 billion US dollars per year. Whether it is NAND Flash or DRAM, the market share of memory chips is small.
