Semiconductor integrated circuit device including semiconductor integrated circuit board supplied with no high voltage

A semiconductor integrated circuit device comprising:

• a wiring board;
• a nonvolatile memory device which is fixed to said wiring board, and which is enabled to electrically program data therein at a first voltage higher than a second voltage, said nonvolatile memory device having a first terminal supplied with said first voltage;
• and
• a semiconductor integrated circuit board, fixed to said wiring board, operable at said second voltage, but not operable at said first voltage,
• wherein said nonvolatile memory device has a second terminal for supplying said second voltage to said semiconductor integrated circuit board,
• wherein said semiconductor integrated circuit board has a third terminal which is electrically connected to said second terminal such that said second voltage is supplied to said semiconductor integrated circuit board, and
• wherein said nonvolatile memory device comprises a voltage converting circuit, disposed between said first terminal and said second terminal, for converting said first voltage into said second voltage when said first voltage is supplied to said first terminal and for outputting said second voltage to said second terminal.
