Abstract:
A memory device includes memory banks that each has multiple rows with row addresses. The memory device also includes a counter that stores and increments a first row address of a first row of a first set of memory banks to a second row address of a second row of the first set of memory banks in response to a first refresh operation when the memory device is operating in a first mode. The memory device further includes circuitry that blocks incrementing the second row address to a third row address of a third row of the first set of memory banks when the memory device transitions from the first mode to a second mode and the first refresh operation is not paired with a second refresh operation that is performed when the memory device is operating in the first mode.
