A refresh control device and a semiconductor device including the same, for preventing a row hammer failure from occurring, may include an enable signal generator configured to generate an enable signal for performing a smart refresh operation and a plurality of active controllers configured to generate a plurality of refresh signals for refreshing word lines located at different positions within one bank, based on receiving the enable signal.

Simultaneous plural wordline within a bank refreshing control device and memory device including the same

A refresh control device may include a fuse array configured to store fuse data. The refresh control device may include a refresh controller including cell arrays including unit cells. The refresh controller may be configured to store position information of a word line having weak cell characteristics based on fuse data. The refresh control device may include a comparator configured to receive data from the cell arrays of a selected cell and may be configured to compare the data to determine the presence of a weak word line to either perform or skip the refresh operation on the corresponding cell.
