| Zusammenfassung: | The present invention relates to a semiconductor integrated circuit having a plurality of input/output buffers for buffering signals inputted/outputted to/from input/output terminals.
Bump areas for signals are spread on upper and lower positions with respect to Vdd and Vss lines in an I/O buffer. Thus, the direction of routing the lines from bumps for signals to the I/O buffers is spread in two directions. A greater number of I/O buffers can be accommodated without increasing the size of a semiconductor integrated circuit. |
