Analysts Call CXMT's 4F² DRAM Threat Overblown

CXMT said it will apply its 4F² DRAM cell structure to server DDR5 chips within the year, potentially two years ahead of Samsung and SK hynix. Analysts at Rosenblatt and KB Securities dismiss the threat as a "paper tiger," saying stable yields, mass production and cost competitiveness still favor the Korean makers, with a 5–7 year DRAM process gap.

• 4F² cuts DRAM cell area by 33% versus the 6F² structure
• Rosenblatt called CXMT's 4F² threat a "paper tiger"
• KB Securities puts CXMT 5–7 years behind Samsung in DRAM
• US export rules limit CXMT's access to EUV lithography
