Flash memory

Flash memory, or more precisely, NAND flash memory chips, stores data on a semiconductor. It is mostly used in the form of USB flash drives to transfer data from one PC to another, or as memory cards that record hundreds of photos in digital cameras. Apple uses flash memory as a substitute for a hard disk drive so it can make its music player only a quarter-inch thick.
Manufacturer prices are starting to rise even though historically the price of flash memory has fallen about 40 percent a year.
