http://www.techreview.com/web/essex/essex072601.asp Faster and cheaper flash memory will empower tomorrow's grabbiest gadgets. By David Essex Flash memory seemed like a miracle chip when it made its commercial debut a decade ago. A new type of electrically erasable programmable read-only memory (EEPROM), it did not need a constant supply of electricity to store data, unlike random-access memory (RAM).... Unfortunately, flash is more expensive to produce than RAM. And that has generally limited capacities of consumer-priced memory cards to 32 or 64 megabytes—confining in a world where 1-MB photographs routinely flit across the Internet. The highest-capacity type, called NAND for the type of logic gate it predominantly employs, also takes far longer to write data than do competing magnetic and optical alternatives. But cheaper and faster flash memory is on its way.... (ed. note: The new Disk on Key is one of many examples of innovative uses of flash ram that may replace some applications of diskettes, zip disks, CD R/W, etc.)
