Abstract
An MOS type read-only memory device having a reduced power consumption has a clock signal generator circuit for generating a pair of positive and negative clock signals by detecting a change of an address signal in the ROM having MOS transistors used as a load and connected to bit lines, a tri-state circuit including an input, a control signal input, and an ouput; the tri-state circuit has its output impedance made higher due to a clock signal supplied to the control signal input. The device also has a switching circuit for keeping the MOS transistors used as a load in their active state based on a clock signal. The inputs and outputs of the tri-state circuit are each connected to the bit lines and gates of the MOS transistors used as a load. The switching circuit is connected to the gate side of the MOS transistors used as a load.
