An apparatus for driving a touchpad of a portable terminal including a second control unit controlling the touchpad in an active mode is provided. The apparatus includes a sensor unit for generating interrupt signals when pressure on the touchpad is sensed, a first control unit for outputting activating signals to activate the second control unit when the interrupt signals are input and a switching unit for transmitting the interrupt signals generated from the sensor unit to the first control unit when the second control unit is in an inactive mode. Accordingly, even though the multimedia processor embedded in the portable terminal is in an inactive mode, the multimedia processor is activated when a user presses the touchpad, thereby making it possible to process signals input by touching the touchpad, particularly, to keep the user interface. Furthermore, the multimedia processor embedded in the portable terminal can reduce the consumption of battery power required to maintain the user interface, as compared with multimedia processors maintaining operating in a conventional polling method.

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.

Memory expansion pack for providing content to portable terminal

An apparatus and method for controlling an operation of a portable terminal having a multimedia function are provided. The apparatus includes a multimedia processor for performing the multimedia function when a controller is in a sleep mode wherein the controller is converted to an active mode when a specified key signal is input into the controller in the sleep mode and outputs an inactive signal to inactivate the multimedia processor. According to the present invention, the portable terminal having the controller controlling the mobile communication function and the multimedia processor controlling the multimedia function, can independently perform the mobile communication function and the multimedia function according to the specified key input. Furthermore, according to the present invention, the controller which controls the mobile communication function need not control the multimedia processor which controls the multimedia function. Hence, it is possible to reduce power consumption and software errors occurring when the controller controls the multimedia processor.
