Introduction
General Description
SanDisk CompactFlash® Memory Card products provide high capacity solid-state flash memory
that electrically complies with the Personal Computer Memory Card International Association
ATA (PC Card ATA) standard. (In Japan, the applicable standards group is JEIDA.) The
CompactFlash Memory Card Series also supports a True IDE Mode that is electrically
compatible with an IDE disk drive. The original CF form factor card can be used in any system
that has a CF slot, and with a Type II PCMCIA adapter can be used in any system that has a
PCMCIA Type II or Type III socket.
CompactFlash Memory cards use SanDisk Flash memory, which was designed by SanDisk
specifically for use in mass storage applications. In addition to the mass storage-specific flash
memory chips, CompactFlash Memory cards include an on-card intelligent controller that
provides a high level interface to the host computer. This interface allows a host computer to
issue commands to the memory card to read or write blocks of memory. The host addresses the
card in 512 byte sectors. Each sector is protected by a powerful Error Correcting Code (ECC).
The on-card intelligent controller in the CompactFlash Memory Card manages interface
protocols, data storage and retrieval as well as ECC, defect handling and diagnostics, power
management and clock control. Once the card has been configured by the host, it appears to the
host as a standard ATA (IDE) disk drive. Additional ATA commands have been provided to
enhance system performance.
The host system can support as many cards as there are CompactFlash and PCMCIA Type II or
III card slots. The original form factor CompactFlash Memory cards require a PCMCIA Type II
Adapter to be used in a PCMCIA Type II or Type III socket.
