ABSTRACT:
In a synchronous semiconductor device, a plurality of input signals having a small amplitude such as an ECL level are converted into a plurality of input signals having a large amplitude such as a CMOS logic level. The large amplitude input signals are held by a plurality of latch circuits and are then supplied to an internal circuit such as a CMOS memory circuit. An ECL level clock signal is converted into CMOS logic level clock signals at a plurality of clock signal conversion circuits. Each of the latch circuits is clocked by the CMOS logic level clock signal generated from one of the clock signal conversion circuits closest thereto.
