ABSTRACT:
A dynamic random access memory device periodically refreshes data bits stored in the memory cells for preventing the data bits from destruction, and an autorefreshing unit incorporated in the dynamic random access memory device is responsive to a CAS-Before-RAS signal control for producing an internal row address strobe signal so that the data bits are automatically refreshed with the internal row address strobe signal in a sequence of self-refreshing cycles without any external signal control.
