FLASH MEMORY Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level. Flash memory is widely used for storage and data transfer in consumer devices, enterprise systems and industrial applications. Flash memory retains data for an extended period of time, regardless of whether a flash-equipped device is powered on or off. Flash memory is used in enterprise data center server, storage and networking technology, as well as in a wide range of consumer devices, including USB flash drives -- also known as memory sticks -- SD cards, mobile phones, digital cameras, tablet computers and PC cards in notebook computers and embedded controllers. For instance, NAND flash-based solid-state drives are often used to accelerate the performance of I/O-intensive applications. NOR flash memory is often used to hold control code, such as the basic input/output system (BIOS), in a PC.

FLASH MEMORY The Flash memory was invented by Dr. Fujio Masuoka while working for Toshiba in 1984. According to Toshiba, the name 'Flash' was suggested by Dr. Masuoka's colleague, Mr. Shoji Ariizumi, because the erasure process of the memory contents reminded him of a flash of a camera. Dr. Masuoka presented the invention at the IEEE 1984 Integrated Electronics Devices Meeting held in San Jose, California. Intel saw the massive potential of the invention and introduced the first commercial NOR type flash chip in 1988. Dr. Fujio Masuoka

FLASH MEMORY How does flash memory work? Flash memory architecture includes a memory array stacked with a large number of flash cells. A basic flash memory cell consists of a storage transistor with a control gate and a floating gate, which is insulated from the rest of the transistor by a thin dielectric material or oxide layer. The floating gate stores the electrical charge and controls the flow of the electrical current. Electrons are added to or removed from the floating gate to change the storage transistor's threshold voltage. Changing the voltage affects whether a cell is programmed as a zero or a one.

Слайд 6

FLASH MEMORY Why it is popular? It saves data when power is OFF. It is non-volatile and hence preserve state without any power. Large and increased capacity High transferring speed, hence it has faster read and write compare to traditional hard disk drives. Small size, portability Low power consumption than traditional hard disk drives Work more quietly than physical hard drive Less prone to damage Cheaper compare to traditional drives in small storage capacities. It does not have any moving parts larger than electrons.
