Abstract
Systems, apparatuses, and methods related to a row hammer refresh operation are described herein. An example apparatus can include an array of memory cells of a memory device. The array of memory cells can include a plurality of dies and at least one of the plurality of dies is a row hammer die. The example apparatus can include a memory controller coupled to the array of memory cells. The memory controller can perform a number of operations on the array of memory cells. The memory controller can detect a quantity of accesses associated with the row hammer die and based on the number of operations performed. The memory controller can, in response to detection of a threshold quantity of accesses of a group of memory cells in the row hammer die, perform a refresh operation on a group of memory cells in an additional die of the plurality of dies.
