SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

PURPOSE:To attain a high speed and small power consumption with a simple circuit constitution for a semiconductor IC device by dividing the array of output lines of an AND array with specific non-inverse and inverse signals to use this divided output line to an input line and therefore dividing also an OR array in the same way to deliver the corresponding output line with a wired logic constitution. CONSTITUTION:Input signals x0 and -x0, for example, are used among complementary input signals consisting of specific non-inverse and inverse signals, and the array of output lines are divided into left and right. For instance, the non-reverse input signal x0 is set at a high level and therefore one of the output line groups of the right side is selected. While one of the output line groups of the left side is selected when the inverse input signal x0 is set at a high level. The enhancement type MOSFETQ5, etc. shown by circle marks are set between the output lines of an OR array and precharge MOSFETQ3, etc. shown also by circle marks. Then the signal -x0 is impressed to the MOSFET of the right side; while the signal x0 is impressed to the MOSFET of the left side. In such a way, an output line of the right side is selected with the signal x0 set at a high level, and at the same time the MOSFET of the OR array (L) of the left side is turned off. Thus a useless precharging action is inhibited.
