    摘要: A semiconductor integrated circuit with memory redundancy circuit to address the problems of increased area, power consumption and access time which is caused by using an ECC circuit for error correction. The circuit includes: a plurality of memory mats; a local bus, parallel to word lines, which transfers read data and write data from memory cells; a global bus for writing, parallel to data lines, which transfers write data from an input pad IO; a global bus for reading, parallel to data lines, which transfers read data to an output pad IO; and at least one error correction circuit located at an intersection of the global buses and the local bus. Reading and writing may each be completed in a single cycle, and during a write operation, data which is different from data previously read is written. By this configuration, an increase in area and power consumption can be avoided and errors such as soft errors can be corrected.

    摘要: The present invention is directed to simplify a circuit for fixing an output logic of a logic gate while suppressing a subthreshold current. A logic circuit has an n-channel type first transistor capable of interrupting power supply to a logic gate in accordance with an input control signal, and a p-channel type second transistor capable of fixing an output node of the logic gate to a high level interlockingly with the power supply interrupting operation by the first transistor, and a threshold of the first transistor is set to be higher than that of a transistor as a component of the logic gate. Means for interrupting the power supply to the logic gate is realized by the first transistor, and means for fixing an output node of the logic gate to the high level is realized by the second transistor, thereby simplifying the circuit for fixing the output logic of the logic gate while suppressing a subthreshold current.
