Production of 4M DRAM chips has resumed after a roughly 10-month halt, according to information reviewed from ten primary sources. The return of the decades-old memory class, once a mainstay of the industry, comes amid renewed demand for legacy semiconductors.
The 4M DRAM, a legacy memory product far below the capacity of today's mainstream DRAM, had been out of production for approximately 10 months before output restarted. Suppliers of legacy memory have been progressively winding down older process nodes, making intermittent production of very low-density chips notable.
While high-density DRAM for AI and data center applications dominates the market, small volumes of legacy DRAM continue to be used in industrial equipment, appliances and other embedded systems. The exact customer base and volume for the resumed 4M DRAM output could not be confirmed from the available sources.
The claim that 4M DRAM production has returned after a 10-month gap is, on balance, Mostly True.
