Imagine if your cell phone worked like your PC.
When you shut down a PC, all the data on a standard memory chip go away. It's wiped clean. That's why PC users store data on hard disk drives before they turn off the PC.
Cell phones are different. They use flash chips, which retain all the data stored on them even after someone turns off the device.
Cell phone companies and other makers of small devices prize flash. It's a way to permanently store software, telephone numbers and the like.
And flash memory is going into more products, from consumer electronics to satellites. Researcher iSuppli says flash sales will have a compound yearly growth rate of 9.3% between 2002 and 2007.
In contrast, it says, DRAMs, the memory chips used in PCs, will grow at a rate of 4.5% over that time. Flash will also represent a larger portion of the overall memory market, though DRAM will keep the lion's share.
