Abstract:
A memory device includes at least one memory bank comprising a set of redundant word lines, a set of normal word lines, and row hammer refresh logic. The RHR logic comprises a first input to receive a first signal indicative of whether a match was generated at a fuse of the memory device, a second input to receive a redundant row address corresponding to a first location of a memory array of the memory device, a third input to receive a word line address corresponding to a second location of the memory array of the memory device. The RHR logic also comprises an output to transmit at least one first memory address adjacent to the first location or at least one second memory address adjacent to the second location based on a value of the first signal.
