1.6. Functional Description
CompactFlash Memory Cards contain a high level, intelligent subsystem as shown in the block diagram, Figure 1-1.
This intelligent (microprocessor) subsystem provides many capabilities not found in other types of memory cards.
These capabilities include the following:
•
Standard ATA register and command set (same as found on most magnetic disk drives).
•
Host independence from details of erasin g and programming flash memory.
•
Sophisticated system for managing defects (analogous to systems found in magnetic disk drives).
•
Sophisticated system for error recovery including a powerful error correction code (ECC).
•
Power management for low power operation.
