ABSTRACT:
A semiconductor device having amplifying circuits provided near corresponding bonding pads receiving external signals, and positioned between the bonding pads and internal circuits to which such external signals are to be applied. The device includes a control signal generating circuit for the amplifying circuits which is not provided in conventional semiconductor devices. In response to external control signals, the control signal generating circuit generates internal control signals for controlling electric paths between a power supply and ground in the amplifying circuits. During the standby period of the semiconductor device, the paths between the power supply and ground are cut regardless of the potential of the corresponding bonding pads, preventing flow of a through current.
