Chinese company ChangXin Memory Technologies (CXMT) has begun mass production of the fifth generation of its DRAM memory platform.
According to ITNA quoting Techspot, the company says the new technology, called the G5 Platform, can compete in manufacturing technology with the world's most advanced mass-produced memory technologies and narrow the gap between Chinese firms and major memory manufacturers like Samsung.
The G5 platform was introduced at the 2026 Global Manufacturing Convention and incorporates a set of new chip fabrication technologies. One of the most important is the self-aligned quadruple patterning (SAQP) lithography technology, which achieves an active area half-pitch for memory arrays of 11.95 nanometers. This technology was developed to increase density and approach advanced memory generations.
CXMT has also used new materials and methods in the chip structure and brought the aspect ratio of the array capacitor to 45:1. The platform also uses an optimized High-k Metal Gate process for DRAM, which has reduced the height of the main cell array to 6,762 nanometers.
One important point about the G5 platform is a 50 percent increase in die-per-wafer density. Such an increase can help improve manufacturing efficiency and energy consumption. To develop this technology, CXMT first created a digital twin of the process to examine design, prototype fabrication, production, and yield management in a virtual environment.
The first mass-produced products based on G5 are two LPDDR5X chips designed for smartphones, laptops, and other portable devices. These chips reach a capacity of 24 gigabits per die, which is 50 percent more than the previous generation.
CXMT's importance in the global memory market is also rising. The company's market value has grown significantly and reports have been published about the possibility of Apple using its chips in consumer products. CXMT is also increasing its wafer production capacity to unprecedented levels; a sign that this Chinese company intends to play a larger role in the global memory market.
