Abstract
A self-refresh method and refresh control circuit of a semiconductor memory device, wherein after the self-refresh mode starts, the burst refresh mode is performed prior to the self-refresh mode; or the self-refresh mode is performed immediately after going into the self-refresh mode, and the burst refresh mode is performed at the completion of the self-refresh mode, and then the burst refresh mode is converted to the normal access mode; or the burst refresh mode is performed before and after the self-refresh mode, thereby shortening a refresh regulation time and securing a stable refresh of the memory cells.
