20 nanometer manufacturing processes, you say? We say pshaw, be gone luddite. Sandisk and Toshiba just announced the latest product from their joint venture: a 19nm 64Gb (8GB) X2 memory chip; aka, the smallest NAND flash memory chip in the world. At least it will be when it hits production in the second half of the year. They are, however, sampling the monolithic chip this quarter in case you're interested in stacking a batch of 16 into an ultra-high density 128GB SSD. Anyone?
