ABSTRACT:
A semiconductor memory device, in which many memory cells formed by transistors having a Schottky barrier transistor as a load are arranged along word lines and the memory cells are driven from one end of the word lines by word drivers. Dummy cells are formed between the word drivers and the memory cells adjacent to the word drivers, so that a forward voltage of the memory cells adjacent to the word drivers is not affected by polycrystalline silicon in the word drivers.
