    摘要: A semiconductor device includes a plurality of drain lines each being commonly connected to first nodes of a plurality of memory cells, a plurality of bit lines respectively connected to second nodes of the memory cells, a source line, a transistor that connects the drain lines to the source line, and a transistor that connects the source line to a ground potential in response to an access to the memory cell. Under control in which the memory cells are all deactivated, the semiconductor device controls the drain line to a drain potential that is higher than the ground potential, and controls the source line to be in a floating state by deactivating the transistors.

    摘要: In the present invention, an inspection contact structure is attached to the lower surface side of a circuit board in a probe card. In the inspection contact structure, elastic sheets with protruding conductive portions are respectively attached to both surfaces of a silicone substrate. The silicone substrate is formed with current-carrying paths passing therethrough in the vertical direction, and the sheet conductive portions are in contact with the current-carrying paths from above and below. The conductive portions on the upper side are in contact with connecting terminals of the circuit board. At the time of inspection of electric properties of a wafer, electrode pads on the wafer are pressed against the conductive portions on the lower side and thereby brought into contact with them.

There are provided MOS transistor TP1, capacitor C1, MOS transistor TP2, and control circuit. MOS transistor TP1 is turned on when overdriving begins, and is designed to supply voltage of power supply VDD1 to parallel-connected sense amplifiers. Capacitor C1 accumulates electrical charges referenced to in association with electrical charges supplied to sense the amplifiers via MOS transistor TP1. MOS transistor TP2 is turned on when overdriving begins, to supply voltage of power supply VDD1 to capacitor C1. The control circuit controls so that MOS transistors TP1, TP2 are turned off when the capacitor potential has reached voltage VREF1. There is also provided a MOS transistor turned on after the MOS transistors TP1, TP2 are turned off to supply a power supply voltage equal to the voltage VREF1 to the plural sense amplifiers.
