Flash memory is used for easy and fast information storage in such devices as digital cameras and home video game
consoles. It is used more as a hard drive than as RAM. In fact, Flash memory is considered a solid state storage device. Solid state means that there are no moving parts -- everything is electronic instead of mechanical.

Here are a few examples of Flash memory:

Your computer's BIOS chip
CompactFlash (most often found in digital cameras)
SmartMedia (most often found in digital cameras)
Memory Stick (most often found in digital cameras)
PCMCIA Type I and Type II memory cards (used as solid-state disks in laptops)
Memory cards for video game consoles
In this article, we'll find out how Flash memory works and look at some of the forms it takes and types of devices that use it.

[line]
Flash memory is a form of EEPROM that allows multiple memory locations to be erased or written in one programming operation. Normal EEPROM only allows one location at a time to be erased or written, meaning that flash can operate at higher effective speeds when the systems using it read and write to different locations at the same time. All types of flash memory and EEPROM wear out after a certain number of erase operations, due to wear on the insulating oxide layer around the charge storage mechanism used to store data.

Flash memory stores information on a silicon chip in a way that does not need power to maintain the information in the chip. This means that if you turn off the power to the chip, the informaton is retained without consuming any power. In addition, flash offers fast read access times and solid-state shock resistance. These characteristics are why flash is popular for applications such as storage on battery-powered devices like cellular phones and PDAs

Flash memory (sometimes called "flash RAM") is a type of constantly-powered nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. It is a variation of electrically erasable programmable read-only memory (EEPROM) which, unlike flash memory, is erased and rewritten at the byte level, which is slower than flash memory updating. Flash memory is often used to hold control code such as the basic input/output system (BIOS) in a personal computer. When BIOS needs to be changed (rewritten), the flash memory can be written to in block (rather than byte) sizes, making it easy to update. On the other hand, flash memory is not useful as random access memory (RAM) because RAM needs to be addressable at the byte (not the block) level.
Flash memory gets its name because the microchip is organized so that a section of memory cells are erased in a single action or "flash." The erasure is caused by Fowler-Nordheim tunneling in which electrons pierce through a thin dielectric material to remove an electronic charge from a floating gate associated with each memory cell. Intel offers a form of flash memory that holds two bits (rather than one) in each memory cell, thus doubling the capacity of memory without a corresponding increase in price.

Flash memory is used in digital cellular phones, digital cameras, LAN switches, PC Cards for notebook computers, digital set-up boxes, embedded controllers, and other devices.

الف الف شكر يالعيناويه ع المعلومات

بس حبيت اسالك انتي من اي مصدر جبتي هالمعلومات

او انك كتبتيها بروحك

مرحبا الغاليه .. المصدر من الانترنت ... يعني في موقع فيه عن هذا الموضوع وحاطين اسم الكتاب وتبحثين فيه ..

ممكن الموقع ع الخاص

وممكن مساعده اكثر ..

معقوله محد يبي يساعدني زياااااااااااااااااااااااااده
