Abstract

A portable memory module facilitates the transfer of data between various processor systems without the need for a physical connection between any of the processor systems and the memory module. The portable memory module includes at least one memory device and a transmitter/receiver circuit for wirelessly (i) receiving data communicated to the memory module and (ii) transmitting data from the memory module. The memory module not only is portable, but is significantly smaller, faster, and easier to use than conventional external hard drives, tape devices, and Zip drives.
