Report: YMTC trails by 1 year on NAND, CXMT by 2 on DRAM and 3 on HBM

The Korea Semiconductor Industry Association says China’s memory-chip industry has narrowed its technology gap with the collective West. The assessment covers YMTC in NAND and CXMT in DRAM and HBM.

According to figures quoted by Korea JoongAng Daily and reported by Wccftech, YMTC is about 1 year behind the West in NAND technology. CXMT trails by about 2 years in DRAM and 3 years in HBM.

The assessment describes the progress as a substantial change from an earlier gap of roughly 5 years in memory-chip manufacturing processes. The available source material does not provide further details about the specific technologies, products, or production facilities included in the comparison.

The figures are attributed to the Korea Semiconductor Industry Association and describe an estimated technology gap. They do not, by themselves, establish that either company has matched the West in every memory-chip process or product category.
