This is a list of DRAM manufacturers and suppliers of dynamic random-access memory integrated circuits. It includes companies that manufacture or market DRAM chips used in DDR SDRAM, LPDDR, GDDR, HBM, and specialty or legacy memory products. Companies that only assemble memory modules from third-party DRAM chips are not included.
Current manufacturers and suppliers
Note: IDM means an integrated device manufacturer that designs and manufactures chips. Fabless / specialty supplier means a company that designs or markets DRAM products while relying partly or wholly on external wafer fabrication.
