Abstract
In order to provide high speed and low 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 portions of the circuit use CMOS elements of low power consumption. This arrangement is particularly advantageous in memory circuits.
