China-made DDR5 memory chips use less advanced chipmaking technology — chips are nearly 40% larger than Samsung’s DDR5
Recently, it turned out that China-based memory maker ChangXin Memory Technologies (CXMT) began to ship DDR5 memory chips. However, according to the findings of a Chinese semiconductor researcher, the die size of CXMT’s 16 Gb DDR5 memory IC is 40% larger than that of a competing Samsung chip, which means that it is significantly more expensive to build due to the use of less advanced chipmaking technology.
