Abstract
A memory expansion pack, which includes a memory for storing content, an FM receiver, an ear jack, and a controller, is connected with a portable terminal through a connector of the pack to provide content to the terminal. Under the control of the controller, content stored in the memory and audio data, which is received through the FM receiver from an external device over a set frequency channel, is transmitted to the terminal. When the ear jack is connected with the external output device, it outputs the content through the external output device. When the ear jack is connected with a device, such as a PC, the ear jack downloads content from the PC. The memory expansion pack allows the user to provide and use a large amount of various content. The pack can also provide high quality services, overcoming the limited memory capacity of portable terminals, and reduce the cost of wireless data communication.
