However, such a method has the following problems. That is, the pitch of the input/output terminals cannot be made so small due to restrictions in bonding with the envelope (package) and restrictions in configuring the input/output circuit. For this reason, especially in a large-scale gate array d'3, there is a drawback that the number of input/output terminals is insufficient compared to the number of internal basic cells. Furthermore, as the number of input/output circuits increases, there is a risk of erroneous reading and latch-up due to fluctuations in the power supply and displacement currents generated when a large number of output circuits are turned on.
