Global competitors have also announced they would jump into the race for V-NAND production.
Micron CEO Mark Durcan told tech news outlet CNET in August that his company would start providing samples of 3-D NAND to customers in the first quarter of 2014.
Producers are competing to scale down planar NAND flash memory, still the top product in the chip market.
After the technology proceeded to the 10 nanometer-class chip and beyond, the chipmakers faced more cell-to-cell interference, which risks the reliability of NAND flash memories.
The 3-D NAND could be used for a wide range of equipment and devices including enterprise servers and solid-state drives.
Samsung launched a V-NAND-based enterprise solid-state drive in August.
