Toshiba start of building a new factory in Japan. Firstly, the plant will be used to make conventional NAND flash chips, but Toshiba is planning to increase production into new types of memory 3D .NAND-type flash memory is possibly the most regularly used . NAND flash memory used in USB pen, memory card, is fixed in devices like digital cameras, mobile phones.

Semiconductor makers continually try hard to better capacity for memory chips by packing their components closer simultaneously, but the engineers are beginning to be anxious that this method could achieve the its limits. As memory cells become smaller, electrical interference between them begins to cause issues. That is why 3D memory appears. July 2010, Toshiba will start building new plants and is probable to stage NAND memory production first began in the after summer of 2011. The production of 20nm process will apply. In an not mentioned time later, the plant will be installed the first production line of Toshiba is capable 3D chip.
