  • Patent number: 9147461
    Abstract: A semiconductor memory device includes a memory cell array and a refresh control circuit. The refresh circuit is configured to: perform a second burst refresh operation on the memory cell rows after the memory cell rows exit from a self refresh operation, and not perform the second burst refresh operation on the memory cell rows after the memory cell rows exit from a self refresh operation. Whether the refresh control circuit performs or does not perform the second burst refresh operation is based on a comparison between an entering time for the self refresh operation of the memory cell rows and a reference time.
