    • A method and apparatus for testing semiconductor devices allows devices to be tested under actual operating conditions by interfacing the devices to an actual board-type product. The semiconductor devices are interfaced to the board-type product with a test board that includes a mounting unit such as a socket or pattern of conductive lands that allows the devices being tested can be easily mounted to and removed from the test board with minimal effort and signal degradation. An interface circuit on the test board compensates for environmental differences between the board-type product and the mounting unit. For example, the interface circuit can include a clock distribution circuit, which utilizes a phase locked loop, and a register circuit to compensate for electrical loading caused by the device mounting unit, and to provide the proper timing margins between clock signals and control signals applied to the semiconductor devices. A power control circuit can be used to manipulate the supply voltage applied to the semiconductor devices, thereby providing a voltage margin screening function.

    • A test system for a semiconductor device couples the device to the back side of a circuit board, thereby allowing the device to be tested under actual operating conditions while providing adequate clearance around the device to accommodate automatic handling equipment, and also reducing signal delay and distortion. A system in accordance with the present invention includes a circuit board having circuitry adapted to provide an actual operating environment for the semiconductor device, as for example, a low cost mother board for testing memory devices. The device is coupled to the back side of the circuit board through test terminals formed on the back side of the board. An interface board can be used to correct the pin arrangements, which are reversed because they protrude from the back side of the board, and to compensate for the environmental differences caused by use of sockets and additional equipment on the interface board.

    • A Personal Navigation System (PNS) and a route guiding method in the PNS are provided. The PNS includes a mobile terminal for transmitting a route guiding request message including its current position information and destination information in response to a route guiding request from a user and a personal navigation server for receiving the route guiding request message, determining the accuracy of the current position information included in the received route guiding request message, providing Route Guiding Information (RGI) according to the current position information and the destination information if the current position information has a high accuracy, and providing destination coordinate information and peripheral map information around a user's current position to provide a direction toward a user's destination if the current position information has a low accuracy. Thus, when initial position of a user is inaccurate, route guiding using the inaccurate initial position is deferred and the user is guided in a direction toward a destination, thereby preventing additional deviation from a correct route due to inaccurate route guiding.
