ABSTRACT:
A semiconductor memory device for driving a word line is provided. The enabling timing of a word line is advanced using a block information signal that contains no redundancy information, thereby improving a RAS to CAS delay (tRCD). A sub word line driving enable signal for controlling a driving of a sub word line and a main word line driving enable signal for controlling a driving of a main word line are controlled by the block information signal that contains only mat information but does not contain the redundancy information. Accordingly, the word line control signal may be activated earlier than the sub word line driving enable signal and the main word line driving enable signal, thereby advancing the enable timing of the word line.
