PURPOSE:To eliminate an erroneous action by the static electricity of an eraseable, programmable ROM, by covering a prearranged area with an aluminium film and keeping it grounded, when a memroy cell circuit including a floating gate and a peripheral circuit including X, Y decoders on a semiconductor, are formed. CONSTITUTION:On one surface of the same semiconductor substrate, a memory cell circuit 6 including a floating gate and a peripheral circuit including X, Y decoders Dx, Dy which adjoin the circuit 6, are formed. Under this constitution, a cell circuit 6 is composed of a floating gate 1, a wiring 3, a contact part 4 connected to the former, etc. In this configuration, approximately half the contact part 4 are covered by an aluminium charge protective film 5 through an insulative film and then are grounded. Likewise, an aluminium film 5 is attached on decoders Dx and Dy and is kept grounded. |
