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

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.
