A semiconductor memory having: a full CMOS-type of memory cell (10) including an n-type bulk access transistor (7, 8), an n-type bulk driver transistor (5, 6) and a p-type bulk load transistor (3, 4) by twos, and a charge capacitance adding charge capacitor element (9) connected to cell nodes (N1, N2) in order to secure a soft error resistance. In the semiconductor memory, an insulating film (14) and a conductive film (15) are directly formed on each upper side of first and second cell nodes (N1, N2) for constituting a charge capacitor element (9) for adding a charge capacitance. The insulating film (14) is held between the cell node (N1, N2) and the conductive film (15), covering both first and second cell nodes (N1, N2) in common.
A semiconductor memory with a plurality of full CMOS-type of memory cells arranged in an array, each memory cell comprising:
