Flash memories are solid state electronic devices with random access memory capabilities used for fast digital information storage. They are used in a wide range of applications, such as storing BIOS routines in typical digital computers, as medium capacity hard drives for digital cameras or as memory cards for laptop computers and video consoles.

The technology used to manufacture flash memories is based on EEPROM (electrically erasable programmable read-only memory) chips, which consist of memory banks formed of storing cells disposed in a grid of columns and rows. A basic storing cell has two MOS-FET transistors at each intersection, and are separated by an oxide layer. The two transistors are known as the floating gate and the control gate.
