FLASH MEMORYBy:

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. Fujio Masuoka, 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 industryMany record labels use jump drives to

save artists music tooThis 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.
