Abstract
This invention relates to a semiconductor memory having flip-flops which hold the address input in order to absorb skew thereof within the same chip. The flip-flops are connected to be of the master-slave type and an address decoder is provided between the master flip-flops and the slave flip-flops. A part of the time required for latching the address signal into the master flip-flops and a part of the time required for decoder operation are overlapped, and thereby a high operation rate can be realized. Parts of the circuits forming the flip-flop circuits are used in common to the address input buffer and also in common to the word line driver circuits.
