Samsung has just rolled out a 30nm 64Gb NAND flash memory chip, which happens to be the world's densest. By packing together the maximum of 16 of the multi level cells, a memory card containing 128GB of storage space can conceivably be created.
Samsung has managed this feat by developing a new process they are calling self-aligned double patterning technology (SaDPT). SaDPT involves a more efficient pattern transfer than used in Samsung's (older) charge trap flash (CTF) procedure, and if we get any more technical we may implode spontaneously. Both procedures are cost effective and we can expect to see higher capacity flash based drives at a reasonable price. Although a 128GB memory card at a realistic price point is optimistic, the general price of flash memory should fall as a consequence of the new development. The devices are planned to begin mass production in 2009 and an estimated market value, in a three year period, is projected to be as high as $20 billion for the new class of memory chips.
