    摘要: An arrangement is provided for preventing DC defects in a memory or logic device after switching to a redundant circuit, improving the product yield of the device by cutting a leakage current path through a defective element or circuit. The cutting points formed by the predetermined wirings as a whole or a part thereof are provided to the device. A probe test of the formed chip is executed under the wafer condition by predetermined test equipment, and wiring correction data regarding the cutting of the cutting points is generated based on the result of test. Moreover, this wiring correction data is transmitted in an on-line fashion to the wiring correction equipment so that the corresponding cutting points can be cut. The wiring correction equipment can be formed by an EB direct writing apparatus, an FIB apparatus or a laser repair apparatus. With this arrangement, the leakage current path formed by a defective element or circuit left unused in conventional circuits is cut, and the product yield of the device is raised significantly. This arrangement can be used for a variety of memory or logic devices, including DRAMs, SRAMs, multiport memories and gate arrays.

    摘要: The present invention is intended to operate a semiconductor device at high speed with low voltage. A circuit configuration is used in which the transfer impedance between a common I/O line and a data line is changed depending on whether information is to be read or written. A current/voltage converter is provided which includes a MISFET different in conduction type to a select MISFET. Thus, the speed of reading information is increased. An intermediate voltage generator having high driving capability is provided. Thus, the circuit has sufficient driving capability for an LSI having large load capacitance. A voltage converter is provided which converts a data line supply voltage or word line supply voltage to a higher voltage. Therefore, stabilized signal transmission is ensured.

    摘要: In a defect relieving technology which replaces defective memory cells of a semiconductor memory device by spare memory cells, use is made of an associative memory. Address information of a defective memory cell is stored as a reference data of the associative memory, and new address information of a spare memory cell is written down as output data of the associative memory. A variety of improvements are made to the associative memory. For instance, a plurality of coincidence detection signal lines of the associative memory are divided into at least two groups, and one group among them is selected by switching means. Reference data of the associative memory comprises three values consisting of binary information of "0" and "1", and don't care value "X". The associative memory further includes a plurality of electrically programable non-volatile semiconductor memory elements.
