2. The working memory in flash drivesis called “flash memory,” inventedby Toshiba in 1980 and availablecommercially since 1988.
3. Flas h Memory• Flash memory is a form of non-volatile computer memory that can be electrically erased and reprogrammed.• Flash memory offers faster read access times and better kinetic shock resistance than hard disks.
4. Flas h Memory• Flash memory generally costs less than other forms of non-volatile memory and therefore has become the dominant technology wherever a significant amount of non-volatile, solid-state storage is needed.• Flash memory is also much smaller and lighter than other forms of non-volatile memory.
5. Flas h Memory• Another allure of flash memory is that, when packaged in a memory card or flash drive, it is nearly indestructible by ordinary physical means, being able to withstand intense pressure and heat.
6. Flas h Memory• There are many manufacturers of flash memory devices and almost as many shapes, sizes and capacities.• Examples of applications include digital audio players, digital cameras, GPS devices and cell phones.
7. Flas h MemoryJust a fewexamples:
8. Flas h Memory• Flash memory can be accessed by the device in which it is contained – Displaying pictures on a digital camera – Playing music on a MP3 player or iPod – Displaying maps in a GPS device – Playing saved messages or downloading ringtones on a cell phone
9. Flas h Memory• Flash memory can also be accessed by a desktop or laptop computer or by a printer• Directly, by connecting the device containing the flash memory to a computer or printer using a USB connection• Or indirectly, via...

24. US B Flas h Drives• USB flash drives are compact and easy-to-use devices that are similar in function to a computer hard drive• USB flash drives slip into your pocket, on a lanyard around your neck or on a keychain for ultimate portable storage
25. US B Flas h Drives• A flash drive consists of a small printed circuit board encased in a robust plastic or metal casing• Only the USB connector protrudes from this protection, and is usually retractable or covered by a removable cap• Flash drives use a standard type-A USB connection allowing them to be connected directly to a port of a personal computer
26. US B Flas h Drives• To access the data stored in a flash drive, the drive must be connected to the computers USB port• Flash drives are active only when powered by a USB computer connection, and require no other external power source or battery power source• They are powered using the limited supply afforded by the USB connection.
27. US B Flas h Drives• Currently, memory capacity ranges from 4GB up to 256GB, limited only by flash memory densities• USB Flash Drives are relatively inexpensive although cost per megabyte increases rapidly at higher capacities due to the expensive components
28. US B Flas h Drives• Based on a recent price check, flash drives were available in retail stores and online at $5 for 4GB, $11 for 16GB, and $65 for 64GB (or about $1 per GB)• A 128GB drive could be had for about $230 and a 256GB version was priced around $700
