Chinese memory-maker CXMT claims DRAM production breakthrough

ASIA IN BRIEF Chinese memory-maker CXMT, whose products Apple has reportedly evaluated to use in the iPhone, claims to have made a miniaturization breakthrough. The company on Sunday posted news that it has started mass production of chips made with a fifth-generation process that essentially doubles memory density, meaning it can cut twice the number of dies for memory chips from a single wafer. CXMT says its key breakthrough is a high-k dielectric metal gate process – a way of insulating silicon to improve efficiency – adapted to baking DRAM. The company claims its new process puts it on par with rival memory-makers. The proof of the pudding is apparently a pair of LPDDR5X memory modules for smartphones or other high-end consumer...
