Abstract:
PURPOSE: A method for electrically testing a chip in a wafer state is provided to reduce a manufacturing cost by eliminating a defective chip in a wafer state, and to improve a productivity of an electrical die test process by simultaneously testing a plurality of wafer chips. CONSTITUTION: A method for electrically testing a chip in a wafer state comprises the steps of: preparing an intermediate connection board having an intermediate connection pattern connected to a bond pad of the chip, the pattern being capable of extending the connected part to the exterior; aligning/fixing a socket board to the intermediate connection board, in which a POGO pin that can be one-to-one connected to the intermediate connection board is established on a bottom surface; and connecting the intermediate connection pattern to the bond pad of the chip.

PURPOSE: A memory module having a socket is provided to easily replace a bad semiconductor device to reduce a manufacturing cost. CONSTITUTION: A memory module includes a plurality of unit memory devices(15), a device mounting region, a plurality of module terminals(13), a substrate, a connecting terminal(24) and a socket(20). The unit memory devices have an outside terminal. The plurality of module terminals is electrically connected to the outside. The memory device is mounted on the device mounting region. The substrate has a line(12) to, electrically, connect the unit memory device. The memory device is inserted in the substrate. As a result, the connecting terminal is electrically connected to the outside terminal of the memory device. The socket maintains a state in which the outside terminal is connected to the connecting terminal by a mechanical compressing force. The connecting terminal and a circuit line corresponding to the connecting terminal are electrically connected.

PURPOSE: A data input and output method using an output circuit operating in a small current is provided to minimize a current consumption by an open-drain output circuit and an input and output system. CONSTITUTION: The output circuit operating in a small current comprises: data output elements(11_i,i=1-8) for receiving read data(RDATi,i=1-8) outputted from a memory element(19) and generating corresponding temporary data(TDATi,i=1-8); a control element(15) for generating a control signal(XCON) after sensing which is greater than the other between the number of real data having a "0" data value and the number of real data having a "1" data value in which the control signal(XCON) controls the data output elements(11_i) and determines the temporary data(TDATi) and the real data(RDATi); output pad elements(13_i,i=1-8) for generating transmission data(ADATi,i=1-8) in response to the temporary data(TDATi), the pad elements having an open-drain structure; and an auxiliary pad element(17) for receiving the control signal(XCON) and supplying an indication signal(XIND) to the exterior.
