ABSTRACT:
A semiconductor read only memory device comprises bit lines, word lines, a load transistor, a multiplexer including a plurality of transistors, and a memory cell array in which each memory cell has one transistor having a gate connected to one of the word lines and corresponding to one of the bit lines connected to the transistors of the multiplexer. A gate transistor is inserted between the load transistor and the multiplexer, and a gate voltage control circuit, for selectively providing a higher level signal and a lower level signal, is connected to the gate transistor.
