Abstract
A correspondence defining circuit changes a correspondence between an external signal and an internal signal and supplies it to a mode designating signal generating circuit according to a logic state of an operation mode switching signal. The mode designating signal generating circuit activates a mode designating signal which designates a specific operation mode in a semiconductor device when the internal signal satisfies a prescribed condition. An operation mode setting circuit, applicable to applications in which states of external signals are different without a change of its internal structure, is thus provided.
