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.
