At present, semiconductor devices represented by DRAM have set off a worldwide price rise. As one of the product types of semiconductor memory, DRAM is commonly used in memory modules. The two main application markets are PC and smart phones. According to the official website of Jingdong Mall, the price of Kingston DDR4 2400 8G desktop has risen from about 400 yuan to about 800 yuan within six months. At the media conference on September 25, Liu Lirong, chairman of Kingston Group, said that the price of domestic mobile phones would still rise in the second half of the year, partly because of the rising cost of memory.

According to the market survey data of Jibang Consulting Semiconductor Research Center, DRAM was seriously in short supply in the fourth quarter of 2016, driving the contract price of the first quarter of 2017 to rise by more than 30%, and the prices of all kinds of products to rise.
