Samsung ramps up production for their 64-layer 3D V-NAND

In recent years, NAND flash production has been one of the fastest growing industries in the PC marketplace, thanks to the growing popularity of SSDs in both custom and pre-built PC systems and the increased use in other mobile devices.Â

Samsung has announced that they have begun volume production of their new 4th generation 64-layer, 256Gb V-NAND, which will be used to create future server, PC and mobile storage applications.Â

The company currently plans on their new 4th generation V-NAND to cover more than 50% of their monthly NAND flash production by the end of the year.Â

This new 3D V-NAND will offer a lot of improved design characteristics over the company’s previous generation 48-layer 256Gb V-NAND, offering 30% more productivity, 20% more reliability and lower operating voltages (2.5V compared to 3.3V) for improved power consumption. This new NAND will also offer a page program time (tPROG) of 500 microseconds, which is 1.5x faster than Samsung’s previous generation NAND. Â

Samsung plans on creating even more advanced V-NAND in the future, stating that they have secured the fundamental technology that is required to produce V-NAND chips with capacities of 1Tb (250GB), which will require over 90 layers of cell arrays.
