Abstract

Numerous features are being added to portable devices including memory intensive ring tones, media files, email and pictures. Existing choices for adding extra memory are difficult and/or expensive to add to the base portable device, especially since many users may not even use them. Extra flash memory can be added to a portable device, but that adds cost to each and every device, and for some users it is never enough, while for others it is too much. It is difficult to balance size and thus cost across the market. The standard way to address extension has been to add some slot in portable devices to hold expandable memory devices such as SD cards and the like. These solutions don't add a great deal of cost, but present difficulties when used with the small packaging/limited board space of typical PDA's, cell-phones, smart-phones, wireless data devices, etc.

A solution is to use Bluetooth, or any other wireless communication mechanism such as ZigBee or GPRS, which is already being added in many high-end portable host devices (e.g. smart-phones, high-end phones, wireless e-mail devices) to add memory with no added cost to the base device.  The memory is added to a seperately packaged and powered accessory device that communicates with the host device via bluetooth.  Extra data that needs to be accessed by the host device resides in the accesso...
