ABSTRACT:
The present invention deals with a semiconductor memory circuit device, in which a memory array portion of a rectangular shape consisting of semiconductor non-volatile memory elements is formed on a main surface of the semiconductor substrate, a low voltage driver circuit (decoder) is formed along a side of the memory array portion, and a high voltage driver circuit is formed along an opposite side of the memory array portion. This permits a reduction in word line length and avoids crossing of the word lines to permit increased operation speed and, particularly, increased reading speed.
