Let it sink in, 20 nanometers. It wasn't that long ago when 45-nm manufacturing processes were all the rage. Now we've got Samsung following Toshiba with a sub-25nm flash memory announcement all its own. Samsung's 20-nm class 32Gb (gigabit) MLC NAND is sampling now, however, for use in embedded memory solutions and SD memory cards ranging from 4GB to 64GB. In addition to increasing densities and decreasing manufacturing costs, Samsung's 20-nm class NAND is claimed to be more reliable and 30 percent faster than the 30-nm MLC chips forming the core of its existing 8GB and h
