2. Points of Discussion
 Introduction of Flash Memory
 History of Flash Memory
 Use of Flash Memory
 Advantages & Disadvantages
 Types of Flash Memory
 New Developments
 Future of Flash Memory

3. Flash Memory
 Flash memory is a non-volatile computer storage
technology that can be electrically erased and
reprogrammed.
 It is a specific type of EEPROM (electrically
erasable programmable read-only memory) that is
erased and programmed in large blocks.
 Flash memory is also known as a solid state
storage device

4. History of Flash Memory
 Flash memory was invented by Dr. Fujio Masuoka while
working for Toshiba in 1980.
 According to Toshiba, the name “Flash" was suggested by
Dr. Masuoka's colleague, Dr. Shoji Ariizumi, because the
erasure process of the memory reminded him the flash of a
camera.
 Dr. Masuoka presented the invention at the International
Electron Devices Meeting (IEDM) in 1984 held in San
Francisco, California.

5. Use of Flash Memory
 Flash memory is used for easy and fast information
storage in computers, digital cameras and home video
game consoles.
 It used in Memory Cards, USB Flash drives and Solid
State drive for transfer of data between computers and
other digital products.

6. 1. Very easily allows to transport documents from one computer
to another.
2. Easy to carry around with.
3. It holds a lot more data than a floppy disk.
4. It is a USB drive so it can be used on any computer system.
5.Better kinetic shock resistance than hard disks.
6. Less power requirement.
Advantages:

7. 1. If you want to hold a big amount of data.
they can be quite expensive to buy.
2. Small so easy to loss.
3. They can take viruses from one computer
to another
Disadvantages:

8. Types of Flash Memory
1. Mobile device memory
2. Compact Flash Memory
3. USB Flash Drives

9. Mobile device memory
MultiMedia Memory Flash Card (MMC)Micro Secure Digital Card (Micro SD Card)

10. Mobile device Memory
 Memory card or Flash card is an
electronic flash memory data storage
device used for storing digital information.
 Used in cellular phones, digital cameras,
MP3 players, and camcorders.

11. Micro Secure Digital Card
(Micro SD Card)
 Micro SD is a small form factor SD card
used in mobile phones.
 When used with its adapter, it is also
compatible with all SD devices.

12. MultiMedia Memory Flash
Card (MMC)
 MultiMedia Memory Flash Card (MMC) is about the size
of a postage stamp.
 It is slightly thinner than an SD Card and can be used in
most the same applications.
 The MultiMedia Memory Flash Card is an ultra-small,
high storage solution for MP3 music players, and global
positioning systems (GPS).

13. Compact Flash Memory

14. Compact Flash Memory
 Compact Flash is a mass storage device
format used in portable electronic devices for
storage.
 The format was first specified and produced by
SanDisk in 1994.

15. USB Flash Drives

16. USB Flash Drives
 USB flash drive consists of a flash memory data
storage device integrated with a USB (Universal
Serial Bus) 1.1 or 2.0 interface. USB flash drives are
typically removable and rewritable,
 These devices plug directly into virtually any USB
port and can support up a massive 32GB of disk
space, all in a compact size.
 All USB Flash Drives are "plug and play" compatible
devices, so the computer will automatically detect
your USB Flash Drives.

18. New Developments
 DINOR (Divided bit-line NOR) Flash
 Attempts to reduce the chip real estate
compared to conventional NOR.
 Low power dissipation, sector erase, high
data transfer rate

19. Future of Flash Memory
 Continues to be among the most
aggressively scaled electronic technologies
 Memory cell size minimum of 20 nm
expected to be met in 2011
 May be replaced by Phase-Change RAM or
other emerging technologies
