ABSTRACT:
A semiconductor memory device which employs a hierarchical word-decode scheme for word selection includes sub-word lines provided for each of column blocks, a control circuit selecting one of the column blocks corresponding to a currently accessed column address in a first case where a currently accessed row address is different from a successively accessed row address, and selecting all of the column blocks in a second case where the currently accessed row address is the same as the successively accessed row address, and a sub-word decoder selectively activating the sub-word lines with respect to all of one or more column blocks selected by the control circuit.
