ABSTRACT:
An address buffer only having (N/2) stages, capable of performing the same function as that of an N-stage address buffer is provided. The address buffer used in a semiconductor device having N (where N is a natural number) additive latency comprises (N/2) serially-connected flip-flops, and an address control circuit which generates an address enable signal in response to a clock signal and a command signal. Each of the (N/2) flip-flops is clocked to the address enable signal and sequentially latches an external address.
