Chinese chipmaker CXMT allegedly used a written roadmap to steal Samsung DRAM tech — South Korean court says ‘Project Hefei’ lifted 620-step recipe to build 10%

Chinese chipmaker CXMT allegedly used a written roadmap to steal Samsung DRAM tech — South Korean court says 'Project Hefei' lifted 620-step recipe to build 10%

About 70% of that money is reportedly going towards further expansion of DRAM production, rather than pricier, more complicated HBM. However, the firm has supplied HBM3E samples to Alibaba's T-Head and Cambricon, even as Samsung and SK hynix enter HBM4 production.

As of the South Korean prosecution's last tally in December 2025, Samsung's damages due to CXMT's alleged machinations ascended to "at least tens of trillions of won." A back-of-the-envelope extrapolation, considering quite a while has passed, might suggest a figure in the range of ₩40 trillion, or $29.5 billion, and rising exponentially.

The lasting impact on the memory market and technology in general is going well beyond plain number descriptors, though. All things considered, if the allegations are true, then CXMT's machinations resulted in a geopolitical-scale economic event. Dr. Evil would be proud.

magbarn I’ll buy CXMT memory as soon as it’s just as good, readily available and cheaper than the triopoly of sk Hynix, Samsung, and micron. The more the Chinese steal from them the better. Reply

S58_is_the_goat Tanakoi said: I'll buy CXMT ram a month after hell freezes over. Chinese firms like this have stolen trillions of dollars of IP from abroad, with the full and complicit assistance of the CCP government: a brutal authoritarian regime that keeps three million of its own citizens in slave-labor genocide camps, and employs an army of two million state agents to censor what the rest of its citizens can read and post to the Internet. Tim Apple: yes but… we still need their memory for our phones. Reply
