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 erasing 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.
•
Implementation of dynamic and static wear-leveling to extend card's life.
