A word line driving circuit includes an address decoding signal generating unit and a word line voltage supply unit. The address decoding signal generating unit includes inverter chain receiving and delaying a first address decoding signal and outputting the delayed first address decoding signal. The word line voltage supply unit includes a pull-up driver that supplies the delayed first address signal to a selected word line in response to a second address decoding signal. The inverter chain includes an NMOS transistor outputting the delayed first address signal and a source terminal of the NMOS transistor receives a set voltage that is higher than a ground voltage and lower than a high voltage.

Word line driving circuit and method

Semiconductor devices are tested under actual operating conditions by interfacing the devices to an actual board-type product, for example, through a test board tat includes a mounting unit such as a socket or pattern of conductive lands that allows the devices being tested to be 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 thereby providing a voltage margin screening function.

Embodiments of the invention allow semiconductor devices to be tested under actual operating conditions by interfacing the devices to an actual board-type product. The 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 to 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. 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 method and apparatus for testing memory devices under actual operating conditions can accommodate non-standard memory devices through the use of an interface board that adapts a non-standard pin configuration to a standard pin configuration on a test substrate. The interface board can include a first surface on which to mount the non-standard device, a pin matching circuit, and a second surface constructed and arranged to couple the pin matching circuit to a standard pin configuration. The interface board can be mounted directly on the test substrate, or coupled to the test substrate through various arrangements of sockets, connection boards, and supports.
