When the miniaturization of a DRAM advances, the capacity of a cell capacitor decreases, and further the voltage of a data line is lowered, the amount of read signals remarkably lowers, errors are produced during readout, and the yield of chips lowers. Expertise of highly trained analysts is employed in a time-efficient manner to write discrete parameterized configuration script templates for maximum re-use, thereby reducing the number of scripts that they are required to maintain and deploy with each update. The apparatus and method of the present invention also blocks an output signal from a first power supply domain from being received in a second power supply domain when the first power supply domain is in a low power mode.
