SanDisk 1.0GB CompactFlash Card
CompactFlash is based on flash memory semiconductor technology. Data, audio, video and images are stored on flash chips rather than the conventional, mechanical, rotating disk drives found in most computers. Flash is non-volatile memory, meaning that once data is saved on the card, it will be retained even if the system's power supply is switched off. Flash is also solid state and has no moving parts. Disk drives have many moving parts and are subject to mechanical problems. Flash is much more rugged and reliable and offers users considerably more protection of data. Mechanical disk drives found in portable computers typically have an operating shock rating of 100-200 Gs, which is equivalent to drop of less than a foot. SanDisks CompactFlash has an operating shock rating of 2,000 Gs, equivalent to a 10-foot drop to the floor.
Flash is sometimes confused with SRAM (static random access memory) semiconductor storage technology. Flash is superior to SRAM in many respects. SRAM storage card typically have low capacities. SRAM requires a battery on board the card to retain data. If the battery expires or battery connections are disturbed with rough handling, the data is lost. Flash is considerably less expensive than SRAM.
SanDisks first CompactFlash cards, built in 1994, were originally based on 32Mbit flash chips built with SanDisks proprietary 0.5 micron technology. CompactFlash was the companys first product to use 32Mbit flash technology and a single chip integrated ATA controller. SanDisk's CompactFlash cards include a controller that handles all the technology-dependent flash memory control algorithms. This integrated controller which stores all IDE (Intelligent Drive Electronics) and ATA commands makes CompactFlash fully compatible with all operating systems, utilities and application programs that support industry-standard IDE disk drives. Full BIOS and driver support for CompactFlash is already built into numerous platforms and operating systems because they currently support the identical PCMCIA-ATA standard. CompactFlash requires no special Flash File systems or drivers. All file management, error correction code, power management and PCMCIA controller I/O functionality is reduced to a single chip. CompactFlash operates on a single supply voltage of 3.3 or 5 volts. This gives CompactFlash the flexibility to work in systems that support only 3.3 volts or only 5 volts.
SanDisk expanded CompactFlash with 64Mbit technology in 1996, 128Mbit in 1998, 256Mbit in 1999 and 512Mbit in 2001. As the density of flash memory increases, considerably higher capacities can be achieved in the same size form factor. Costs also decrease and consumer prices decline as higher capacities can be obtained from the same number of silicon wafers. Demand for more storage always increases with time.
