#Samsung will have 64-layer #3DNAND in mass production before #WesternDigital (WD)/ #Toshiba and is looking into #3DXPoint memory alternatives. With WD/Toshiba announcing that their 64-layer 3D NAND has started production, the timing is exactly right for Sammy to say it will have its own 64-layer 3D NAND in mass production by the end of the year. WD/Toshiba’s initial 256Gbit chip should be in mass production before the middle of 2017, up to 6 months later than Samsung. A Samsung representative on an earnings call said: “Our goal is to mass-produce SSDs that use our 4G V-NAND within the year.” In the call Sewon Chun, from Samsung’s memory marketing team, said: “Our development plan for fourth-generation V-NAND and mass production of 18nm DRAM is progressing smoothly.” This 4th-generation V-NAND is a 64-layer technology. He added: “Although overall demand is expected to increase, thanks to increased demand for high-density solution products in major SSD and mobile applications, supply and demand is expected to become much tighter in the second half due to supply restrictions caused by 3D NAND ramp-up delays in the market.”
