CompactFlash (CF) is a type of storage device data, especially useful for portable electronic devices. It can be used directly in a CF card slot with an adapter. It uses flash memory. On the basis of physical characteristics, there are two types of Flash Cards: Type I (3.3mm thick) and the thicker Type II (CF2) cards (5mm thick).

First produced in 1994 by SanDisk, Compact Flash is among the earliest and most ancient and also marks the most successful and is now used for a wide range of devices, including laptops, portable audio recorders and desktop computers and cameras.

Flash memory devices for energy is much smaller and has transfer speeds well. They can also be turned from one system to another. They are also designed to accommodate the rapid changes in temperature or voltage. The storage capacity ranges from a CompactFlash card from 128 to around 64 GB. However, 256 MB and 2 GB is the most popular choice in Europe.

Flash memory has a special quality that allows some of its memory cells never erased at once, very similar to a function of the camera flash. It recalls the ease of erasing data can be carried out, freeing space for new data on net. Flash memory is non volatile and solid state can be electrically erased and rewritten. Flash memory allows more memory to be erased or written in a programming operation. It can operate to read much higher access speeds. Improving resilience to shocks, as hard drive is another of his properties. For these features make cards are much better on other devices like cell.

A limitation of this card is so easily rewritable memory that can be overwritten without warning lead loss of data. System failure, power fluctuation, corruption as a result of accident or equipment malfunction software has other limitations.

Flash memory stores one bit of information in an array of transistors, called "cells". Compact Flash cards are built based on the type of logic gate used in each bin and are of two types: NOR flash and NAND Flash. Recently, however, some flash memory devices device known as multi-level cell can store more than one bit per cell. NOR Flash cell has two doors: the door control and grid liquid. NAND Flash is a second mechanism: tunneling injector to writing and tunnel release for erasing.
Demand in the market today is tilting against low prices for NAND flash memory.
