ABSTRACT:
In a dynamic Random Access Memory having memory cells arranged in a matrix shape, one of row decoders is designated so that the data stored in the memory cells of a row corresponding to the designated row decoder are read out. Subsequently, a row address for refreshing the memory cell array is automatically generated by a refresh address counter which is located in the dynamic Random Access Memory, thereby, the memory cells on the row of the memory cell array are refreshed without any external refresh control unit.
