WED7GxxxIDE36

The DimmDrive WED7GxxxIDE36 is a high performance single chip flash disk IDE module with Power Failure Protection Circuit available in 144 Pin SO-DIMM package.The DimmDrive WED7GxxxIDE33 does not have the additional PFP circuit.

The additional circuit provides protection against accidental power loss. This circuit provides an internal power supply and control logic to stop receiving data and complete writing the last sector of data received. This is not intended to be backup for the host system. It will only allow the last sector received to finish writing and no more. It will improve card integrity in applications with a high risk of power failure. The read/write unit is 1 sector (512 bytes) sequential access.

The module is based on SanDisk NAND Flash technology and utilizes 128Mb, 256Mb, 512Mb or 1Gb memory components to provide the maximum in module density.The DimmDrive WED7GxxxIDE36/33 utilizes a SanDisk Flash ChipSet 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 WED7GxxxIDE36/33 module will have the same functionality and capabilities of an intelligent ATA (IDE) disk drive. Once the device has been configured by the user, it appears to the host as a standard ATA disk drive.

The on-board controller is a highly integrated solution 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 WED7GxxxIDE36/33 module also provides a more cost effective solution to the traditional hard disk media. The module is perfect for applications requiring upgrade ability 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 with IDE pinout and you then have a bootable flash disk.The DimmDrive WED7GxxxIDE36/33 is available with memory densities of 16MB to 2GB.
