<P>PROBLEM TO BE SOLVED: To provide a semiconductor circuit device which can effectively use a once-developed flash memory by previously arranging preliminary input/output pads and by only adding a metal wiring layer. <P>SOLUTION: In the semiconductor circuit device having the input/output pads, preliminary input/output pads are arranged on a dead space 204 in a position region of input/output pads 102a. Since a mask formation cost is reduced and the number of diffusion steps is reduced by making possible to switch input/output arrangements, a development schedule can be shortened. Switching between the input/output pads 102a and the preliminary input/output pads is enabled by using a single wiring layer or contact layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
