ABSTRACT:
In order to provide high speed and lower power consumption, a semiconductor integrated circuit is constructed to utilize both CMOS elements and bipolar transistors. The bipolar transistors are used in the output portions to take advantage of their speed of operation to allow rapid charging and discharging of output lines. In the meantime, the principal operating portiosn of the circuit use CMOS elements of lower power consumption. This arrangement is particulary advantageous in memory circuits.
