Roundhill Memory ETF (DRAM) has added GigaDevice to its holdings with a 2.91% weighting, according to public information. Citrini Research analyst Jukan said GigaDevice is viewed as the parent company or an affiliated entity of Chinese DRAM maker CXMT. The ETF tracks the global memory chip supply chain and lists Samsung Electronics, Micron Technology and SK hynix among its core holdings, placing GigaDevice within a portfolio of major memory-sector names and potentially widening international investor exposure to companies linked to China’s domestic DRAM industry.
