    • Flash Memory
      By:
      Aaron Miles
    • What is Flash Memory?
      It is “a non-volatile computer storage that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products.” Wikipedia
    • History
      Founded in 1980 by Dr. FujioMasuoka, an employee of Toshiba.
      The name “flash” was suggested by Dr. Masuoka’s assistant, Mr. Shoji Ariizumi.
      In 1984 he presented his idea at the IDEM.
    • History
      In 1987 Toshiba release a NAND based flash memory.
      This unit had faster erase and writing times
      Smaller in size with more memory
      This product was also a lower cost than NOR based flash memory
    • History
      In 1988 Intel Corporations release a NOR based flash memory.
      This product has a long erase and writing times.
      NOR based flash memory has an endurance of 10,000 to 1,000,000 erase cycles.
      Provided full addresses and data buses which allowed full access to memory in every location
    • Functionality
      Flash memory is a very complicated technology in its processes
      It consists of two transistors.
      Floating gate
      Control gate
    • Functionality
      Flash memory also contains cell sensors.
      This system here monitors the level of the charge passing through.
      Oxide layer
      Acts as a barrier between the floating gate and control gate
    • Usage in Society
      “Provided 9.1 million in production and sale in 2008” according to Wikipedia.
      Used in memory sticks for digital cameras, camcorders, and mobile phones.
      High demand for college students
      This device is used often by college students as a second hard drive for their school work.
    • Usage in Society
      Apple INC.
      In 2008 apple was counted for 13 percent of flash memory sales.
      Apple also has and MP3 player that plugs directly into your computer through a USB.
      Flash memory has even hit the music industry
      Many record labels use jump drives to save artists music too
      This also allows easy music transportation
    • Usage in Society
    • Future Trends
      This field of technology has grown rapidly since its discovery.
      Mobile Phones
      Flash memory wants to make mobile phones have their main storage be memory cards.
      Flash memory wants to take over hard drives
      They still have not produced something with the capacity of a hard drive.
    • Future Trends
      Flash Memory to slow down?
      This technology is at a stand still with size and memory.
      Companies still haven’t developed a flash memory device with enough memory due to there lack of size and space to fit gigabyte’s.
