    Abstract: A semiconductor memory device includes a self-testing circuit and a self-redundancy circuit with simple structures. The self-testing circuit includes a comparison circuit which compares write data with read data with respect to normal memory blocks and redundant memory blocks, and a decision circuit which decides if the semiconductor memory device is good or defective based on the plurality of comparison result signals. A signal transfer and holding circuit is connected between the comparison circuit and the decision circuit to transfer the plurality of comparison result signals to the decision circuit and to supply the plurality of comparison result signals to the self-redundancy circuit as a test result.

    Abstract: A testing device can perform a test on an arbitrary one of a plurality of semiconductor devices by pressing the semiconductor devices onto a contactor from a back side of the semiconductor device. A test circuit board has a contactor provided with contact pieces corresponding to external connection terminals of semiconductor devices to be tested. A support board is capable of mounting the semiconductor devices thereon in an aligned state. A stage supports the support board. A press head presses the semiconductor devices to be tested mounted on the support board so as to cause external connection terminals of the semiconductor devices to be tested to contact with the contact pieces of the contactor. The stage is movable to a position at which at least one of the semiconductor devices to be tested, which are mounted on the support board, faces the contactor.

    Abstract: A contactor for electronic parts can provide an appropriate and uniform contact with respect to a plurality of electrode terminals in an electronic part such as an IC. Each of a plurality of contact members has a first contact portion on one end thereof and a second contact portion on the other end thereof, the first contract portion having a recessed portion that receives one of the electrode terminals of the electronic part. A base accommodates and supports the plurality of the contact members. The first contact portion is movable in a horizontal direction.
