  • Patent number: 10446216
    Abstract: Embedded refresh controllers included in memory devices and memory devices including the embedded refresh controllers are provided. The embedded refresh controllers may include a refresh counter and an address generator. The refresh counter may generate a counter refresh address signal in response to a counter refresh signal such that the counter refresh address signal may represent a sequentially changing address. The address generator may store information with respect to a hammer address that is accessed intensively and may generates a hammer refresh address signal in response to a hammer refresh signal such that the hammer refresh address signal may represent an address of a row that is physically adjacent to a row of the hammer address. Loss of cell data may be reduced and performance of the memory device may be enhanced by detecting the intensively-accessed hammer address and performing the refresh operation based on the detected hammer address efficiently.
