ABSTRACT:
A semiconductor non-volatile memory device, has plural data storage parts which are connected in series between the source region and drain region. In such a constitution, when integrating the semiconductors, the relative area occupied by the selection gate, separation gate, source region and drain region of the area of the data storage parts may be drastically reduced, and the degree of integration of the semiconductor non-volatile memory device can be dramatically enhanced. The device also allows for setting the semiconductor substrate in a depletion state by sequentially varying the gate potential of the plural data storage parts and transferring the electric charges sequentially. By this transferring of electric charges, data write errors may be prevented.
