Abstract
An address decoder circuit of the present invention forms a word line selection signal by entering an m-bit address signal by dividing it into two groups of i bits and (m-i) bits. The decoder output from the i-bit signal is inputted to the gate of a first enhancement-type MOS transistor and that from the (m-i)-bit signal is applied to its source. Its drain is connected to a word line of a memory cell array. An inverter is provided to invert the decoder output from the i-bit signal and the output from the inverter is applied to the gate of a second enhancement-type MOS transistor of which the drain and the source are connected respectively to the word line and a power source terminal.
