Abstract
An input first stage is used for inputting both addresses and address keys. A test mode setting circuit and a function setting circuit are disposed between the input first stage and an address buffer. Each function setting mode buffer latches an internal address signal when a signal/RAS falls. Further, a function signal generating circuit is initialized by a power-on reset signal when a power supply is turned on.
