ABSTRACT:
A programmable semiconductor memory device provided with a read word line driver and a write-only word line driver. The write-only word line driver is disconnected from the lines after a write operation. The read word line driver has read-driving output transistors, the emitter areas of which are smaller than the emitter areas of the write driving output transistor. Thus, the accessing speed for a read operation is improved.
