Samsung is converting its last 2D NAND production line to produce 1c DRAM, although the specifics of the conversion, including the exact facility and the potential for other uses such as HBM4 production, are not clear. This move, along with Kioxia's planned exit from 2D NAND, has reportedly led to a significant increase in MLC NAND prices. The shift away from 2D NAND production may mark a turning point for the memory industry.
