DESCRIPTION

The DimmDrive WED7GxxxATA33 is a high performance single
chip flash disk module available in 144 Pin SO-DIMM package.
The module is based on SanDisk NAND Flash technology and
utilizes the 128Mb, 256Mb, 512Mb or 1Gb memory components
to provide the maximum in module density.

The DimmDrive WED7GxxxATA33 utilizes a SanDisk Flash ChipSet
controller which is designed specifically for use as a Flash mass
storage controller for the SanDisk memory devices. This inter­face allows a host computer to issue commands to read or write
blocks of memory in the Flash memory array. The intelligence to
manage the interface protocols, data storage and retrieval as well
as ECC, defect handling and diagnostics are controlled by this
device. Automatic power management and clock control is
handled by the controller as well.

The DimmDrive WED7GxxxATA33 module will have the same
functionality and capabilities of an intelligent ATA (IDE) disk
drive. An advantage of the on board Flash controller and it's ATA
command set, is the ease of software development by the user.
Once the device has been configured by the user, it appears to the
host as a standard ATA disk drive. Additional ATA commands
have been provided to enhance the system performance.

The on-board controller is a highly integrated solution and the
controller is designed to handle all intelligent operations, even the
rare cases when new defects arise and need to be mapped out or
replaced by a spare. The hardware performs the complicated
task of ECC detection and correction and will return good data to
the host. The controller manages all defects and errors and
makes the Flash memory appear as perfect memory to the host.

The DimmDrive WED7GxxxATA33 module also provides a more
cost effective solution to the traditional hard disk media. The
module is perfect for applications requiring upgradeability to
higher densities and for those applications with limited space
availability and power consumption requirements.

Unlike standard IDE drives, no cables or extra space is required.
The module has no moving parts providing significant reduction
in power consumption and increasing reliability. Simply insert the
module into a standard 144 Pin SO-DIMM socket and you then
have a bootable flash disk.

The DimmDrive WED7GxxxATA33 is available with memory
densities of 16MB to 768MB today with 1GB density available in
Q3/02.
