Abstract
First and second inverting stages and first and second decoding stages form in combination a decoder circuit, each of NAND gates of the first and second decoding stages and each of inverters of the first and second inverting stages are implemented by bi-MOS circuits, respectively, and the bi-MOS circuit for the NAND gate and the bi-MOS circuit for the inverter are a high-speed large-current consumption type and a low-speed small-current consumption type so that the decoder circuit achieves a high switching speed without sacrifice of power consumption.
