CompactFlash on IDE Bus
solid-state memory for the PC
CompactFlash cards are memory media that retain their contents without a supply voltage. They are used in digital cameras, among other things. Thanks to the ‘intelligence’ present in such a card, it can also be easily connected to a PC, for example for use as a ‘solid-state drive’. The supersimple adapter described here makes it easy to connect all types of CompactFlash cards to a PC.A CompactFlash card is a small memory card, originally developed by Sandisk, with dimensions of approximately 4×4 cm. Since it uses non-volatile memory cells, the contents of the memory are retained for years, even without a separate source of power. Such cards are used particularly often in Digicams. Presently, the memory capacity can be as much as 1 GBytes. IBM, by the way, even supplies mini hard disks in CompactFlash format with capacities of up to 1 GBytes.
