Abstract
A semiconductor integrated circuit can variably set the driving power of all or part of internal input/output terminals and internal output terminals used within a multi-chip package. It can increase the driving power at an individual wafer test before packaging to sufficiently drive a load connected between a tester and the internal input/output terminals and internal output terminals, and can reduce the driving power after packaging. It can prevent noise and power consumption from being increased.
