Global NAND memory bit market share 2018, by application

The data displays a forecast for the distribution of demand for NAND memory bits worldwide in 2018, broken down by device segment. In 2018, 37% of total NAND memory capacity will go towards smartphones. NAND flash memory was originally developed by Toshiba in the early 1980s. It allows greater storage density and lower cost per bit than the alternative NOR flash, but is more useful as a secondary storage device than as primary storage, as it does not support a random-access external address bus.
