description A semiconductor memory device having a flexible refresh skip area includes a memory cell array including a plurality of rows to store data, a row decoder connected to the memory cell array, a refresh area storage unit to store a beginning address and an end address of a memory area that is to be refreshed in which the memory area that is to be refreshed does not include a refresh skip area having a size is selectively and/or adaptively changed, and a refresh control circuit connected to the row decoder and the refresh area storage unit. The refresh control circuit controls a refresh operation for the area that is to be refreshed and not for the refresh skip area.
