    摘要： An SRAM disclosed herein includes 64 memory cell array blocks and a redundant memory cell array block. The redundant memory cell array includes a total of 16 redundant memory cell columns. A defect address indicating a location of a defective memory column is programmed in an address programming circuit, and the specific defecting column in the defect address is programmed in an I/O programming circuit. Although each memory cell does not include a spare memory cell column or row for redundancy, the defect can be repaired by using a redundant memory cell array, so that the high integration of the SRAM can be accomplished.

    摘要： An improved flash EEPROM with a sense amplifier having a sensing characteristics suitable for sensing a data signal under an externally applied supply voltage Vcc in a lower range, and a sense amplifier having a sensing characteristics suitable for sensing a data signal under the supply voltage Vcc in a higher range. A Vcc level detecting device detects in which range the supply voltage Vcc is in, soasto selectively enable one of sense amplifiers. Since the data signal is amplified using the sense amplifier having the optimum sensing characteristics in accordance with the level of the supply voltage, the stored data can be accurately read.

    摘要： In an exhaust system, there are provided an HC absorbent which absorbs HC contained in exhaust when in a specified low-temperature range and desorbs the absorbed HC when it exceeds said low-temperature range, and a catalyst capable of at least removing HC by oxidation, where the catalyst is arranged at the same position as or downstream of the HC absorbent. When it is found that the HC absorbent is in a state ready for desorbing the absorbed HC (S16, S18) and the internal combustion engine is in a specified decelerating state (S14), fuel supply to some of the cylinders of an internal combustion engine is stopped while fuel is supplied to the other cylinders (partial fuel cut) (S22).
