Abstract

PURPOSE:To prevent the malfunction due to leakage current, by providing the discharge time constant circuit having that for the logic block. CONSTITUTION:Although the load capacitance is interrupted from each logic block with the non-conduction of switching MISFET Q7 to Q7''' and the discharge of the logic block Ri selected is inhibited, since the discharge time constant is the same as the output R0 of the dummy logic block, then the storage level of the output Ri is regarded as low level logically. On the other hand, the output Rj of the logic block of non-selection is inhibited for the decrease in the hold level with the decrease in MISFET group even with more or less leakage current due to pattern deficiency.
