ABSTRACT:
The present invention relates to a semiconductor device with a daisy chain structure having an independent, wherein each of the independent refresh means is additionally added to each of DRAMs being formed in a ring type, thereby independently performing a refresh operation in each DRAM to replace the conventional refresh operation depending on the existing single controller so that it allows easy application the semiconductor device by decreasing a DRAM's dependency to the controller.
