The M-Systems DiskOnChip 2000 (DOC-2000) family of
products provides a single chip solid-state flash disk in a standard
32-pin DIP package. The DOC-2000 is a small, plug-and-play,
solid-state disk with no moving parts, resulting in a significant
reduction in power consumption and an increase in reliability.
The DOC-2000 family of products is available in capacities
ranging from 2MB up to 72 MB, unformatted. This way, the same
socket on the target platform will not have to be changed. In order
to manage the disk, the DOC-2000 includes the TrueFFS, M-
Systems Flash File System proprietary software. The DOC-2000
package is pin-to-pin compatible with standard 32-pin EPROM
devices.
