Micron Technology, one of the world's leading memory manufacturers, has recently announced its decision to discontinue the production of DDR4 memory and focus on the development and production of DDR5, LPDDR5, and HBM4 memory technologies. This move has significant implications for the memory industry, as all three major memory manufacturers, including Samsung, SK Hynix, and Micron, have now abandoned DDR4 production. Despite the ongoing demand for DDR4 memory, this shift may lead to a temporary increase in prices, with DDR4 potentially surpassing DDR5 in cost. However, it is likely that Chinese companies, such as CXMT, will continue to produce DDR4 memory, which may help to mitigate the price increase. The discontinuation of DDR4 production by Micron and other major manufacturers is a significant development in the memory industry, and it will be interesting to see how this shift affects the market in the coming months.
