As you might have guessed already, Samsung and Toshiba are the two largest players in the global NAND flash memory market but the game between their sales has never exceeded $6 billion until last year.
Samsung's utter dominance in this market is now expected to continue for a considerable amount of time as its manufacturing technology is progressing faster than the competition. Toshiba may not be able to catch up with Samsung quickly given that it's facing a few hurdles in trying to increase its investment in 3D NAND flash memory production facilities.
