    Abstract: Predictive memory maintenance in accordance with one aspect of the present description, can anticipate a failure of a selected primary memory die of an array, and pre-load a spare memory die with the data of the selected primary memory die deemed to have a likelihood of failure, prior to any actual failure of the selected memory die. In the event that the selected primary memory die does subsequently fail, the spare memory die pre-loaded with the data of the selected primary memory die can readily take the place of the failed primary memory die with a pre-existing copy of the data of the failed primary memory die. Other aspects are described herein.

    Abstract: A write history buffer can prevent write disturb in memory, enabling a reduction in write disturb refresh rate and improvement in performance. A memory device can include circuitry to cause consecutive write commands to the same address to be spaced by an amount of time to reduce incidences of write disturb, and therefore reduce the required write disturb refresh rate and improve performance. In one example, a memory device receives multiple write commands to an address. In response to receipt of the multiple write commands, the first write command is sent to the memory and a timer is started. Subsequent write commands that are received after the first write command and before expiration of the timer are held in a buffer. After expiration of the timer, only the most recent of the subsequent write commands to the address is sent to the memory array. In this way, the subsequent write commands received during a time window after the first write command are coalesced and a single subsequent write command is sent to the memory.
