    摘要: A delay circuit is interposed between first and second circuit systems both driven by a first supply voltage. The delay circuit delays a signal applied by the first circuit system, and then transmits the delayed signal to the second circuit system. In particular, a constant voltage supply circuit generates a second supply voltage (constant voltage) on the basis of the first supply voltage, and supplies the constant voltage to this delay circuit, so that a stable constant delay time can be obtained by the delay circuit without being subjected to the influence of fluctuations of the first supply voltage. All the circuit elements are formed on the same semiconductor substrate. Further, it is preferable to construct the constant voltage supply circuit in such a way that the output voltage thereof is programmable.

    摘要: A memory cell array includes static memory cells arranged in an array of n rows.times.m columns. Each of the memory cells includes MOS transistors formed in a semicondutor substrate and in a corresponding one of well regions of the conductivity type opposite to that of the semiconductor substrate. The well regions are independently formed for each row or for every two or more rows of the memory cell array. The well regions are connected to the respective sources of MOS transistors formed in the well regions. The source and backgate of each of the MOS transistors formed in the well regions are connected to the common source wirings for each of the independently formed well regions. Isolation circuits are respectively connected between the common source wirings for the repective well regions and the power source. A row of the memory cell array to which a defective memory cell is connected is isolated from the power source by means of the isolation circuits.
