Abstract
A semiconductor memory having: a full CMOS-type of memory cell ( ) including an n-type bulk access transistor ( ), an n-type bulk driver transistor ( ) and a p-type bulk load transistor ( ) by twos, and a charge capacitance adding charge capacitor element ( ) connected to cell nodes (N N ) in order to secure a soft error resistance. In the semiconductor memory, an insulating film ( ) and a conductive film ( ) are directly formed on each upper side of first and second cell nodes (N N ) for constituting a charge capacitor element ( ) for adding a charge capacitance. The insulating film ( ) is held between the cell node (N N ) and the conductive film ( ), covering both first and second cell nodes (N N ) in common.
